300+ TOP MCQs on Cloning in Lambda – 1 and Answers

Genetic Engineering Multiple Choice Questions on “Cloning in Lambda – 1”.

1. Insertion vectors are a type of vectors. Choose the correct statement for this type of vector.
a) These are complex vectors
b) DNA is inserted through many restriction sites
c) There is an upper limit on the size of the DNA to be packaged
d) Lambda gt09 is an example of this type of vector
Answer: c
Explanation: Insertion vectors are the simple vectors and DNA is inserted through a single restriction site. It must be a non-essential gene to maintain phage viability. There is an upper limit on the size of the DNA to be packaged thus only a few kilobases of the extra DNA can be included. Lambda gt10 and gt11 are an example of insertion vectors.

2. Choose the correct statement for lambda gt10.
a) It is having an EcoRI site
b) It is having cII gene
c) It accepts an insert of size greater than that of 8 kbp
d) This size is less than that the size which is generally accepted by wild type phage
Answer: a
Explanation: Lambda gt10 is having an EcoRI site which contains the cI repressor gene. It accepts an insert of size upto 7.6 kbp which is generally more than that of the size generally accepted by a wild type phage.

3. The presence of insert leads to inactivation of which gene?
a) cII
b) cI
c) cIII
d) both cII and cIII
Answer: b
Explanation: The presence of insert leads to inactivation of the cI gene and this is the method to detect the presence of an insert.

4. A portion of phage is removed and in place of it, the DNA of interest is inserted. This type of vector is called as __________
a) displacement vector
b) insertion vector
c) substitution vector
d) transposition vector
Answer: c
Explanation: If a portion of phage is removed and in its place, the DNA of interest is inserted, it is called as substitution or replacement vector.

5. Choose the incorrect statement for the central portion of the lambda genome.
a) The central portion is not required for lytic growth
b) The central portion includes repressor gene
c) The repressor gene is not required for lysogenic growth
d) It is approximately 10kbp long
Answer: d
Explanation: The central portion of the lambda genome is approximately 20 kbp and it is not required for lytic growth. The central portion constitutes of repressor gene and thus it has to be removed for the lysogenic growth to take place.

6. The fragment inserted in the place of the central portion of the genome is known as __________
a) insertion fragment
b) substitution fragment
c) stuffer fragment
d) displacement fragment
Answer: c
Explanation: The fragment inserted in the place of the central portion of the genome is known as the stuffer fragment. It is generated by doing partial digestion an enzyme having a 4bp long recognition site.

7. Choose incorrect statement for the substitution vector EMBL4.
a) It is having two single multiple cloning sites
b) The region to be removed is on one side of the multiple cloning sites
c) If a digestion within the multiple cloning sites, it generates central portion and right and left arms
d) The right and left portions are called as arms
Answer: b
Explanation: The substitution vector EMBL4 contains two multiple cloning sites. The two multiple cloning sites flank the region which is to be removed. If digestion is done within the multiple cloning sites, it generates central portion and the right and left portions. The right and left portions separated are known as arms.

8. Is it necessary to stop the relegation of the central portion before the stiffer fragment is ligated.
a) True
b) False
Answer: a
Explanation: The central portion should be stopped from religating before the stuffer fragment should be ligated. There are chances that central portion gets religated to the arms.

9. At times, a second enzyme is used while the central portion is removed and the stuffer fragment is placed there. Choose the statement which doesn’t holds for this process.
a) It is a method which is used for avoiding the relegation of central portion before the stuffer fragment is attached over there
b) In this method, the central portion is cut with another enzyme after being separated from the arms
c) The arms are also cut with this second enzyme
d) It is not necessary to remove the fragments generated
Answer: c
Explanation: A second enzyme is used in order to avoid the relegation of the central portion and the arms. In this method, the central portion is cut with a second enzyme after being separated from the arms. These arms are not cut with the second enzymes. Hence the ends created are different now and the arms won’t ligate to the central portion again. It is not necessary to remove the fragments generated because the chances of having a multimolecular reaction which are required for the formation of original phage are very less.

10. Physical separation is also used at times. Choose the correct statement with respect to this method.
a) Physical separation constitutes of gel electrophoresis and or by using centrifugation in sugar density gradient
b) In sugar density gradient, the molecules are separated on the basis of density
c) The central portion is recovered from the gel or the gradient
d) Gel is more efficient than the sugar density gradient
Answer: a
Explanation: Physical separation is also used at times, it constitutes of using gel electrophoresis or by using centrifugation in the sugar density gradient. In the sugar density gradient, the separation is done on the basis of size. The arms are separated from the gel or gradient. A gradient is more efficient than gel, thus gradient is more preferred over the gel.

11. Packaging in vitro is also carried out to introduce the lambda DNA into the cells. Choose the incorrect statement in respect to it.
a) Packaging in phage coat is a more efficient process than the normal transformation process
b) The lambda DNA is incubated with lysate of lambda infected cells in a concatemeric configuration
c) Lysate constitutes of lambda proteins needed for phage assembly
d) The amount of non-recombinant phage in the background is less
Answer: d
Explanation: Packaging in vitro is used to introduce the lambda. It is more efficient than the normal transformation procedure. Thus, the lambda DNA is incubated with lysate of lambda infected cells in a concatemeric configuration. This lysate constitutes of lambda proteins needed for phage assembly and hence the recombinant DNA is also packed. But there is also a large amount of non-recombinant packaging in the background.

12. Packaging in vitro is basically carried out by two different strategies. Choose the incorrect statement for it.
a) Separate strains with chain-termination mutations in different genes for coat components are used __________
b) Temperature sensitive cI repressor is used
c) Due to heat shock packaging proteins are induced
d) Packaging is carried out in each strain
Answer: d
Explanation: Packaging in vitro is basically out by two different strategies. In the first strategy, separate strains with chain-termination mutations in different genes (mostly D and E genes) for coat components are used. Temperature sensitive cI repressor is used and due to induction by heat shock, packaging proteins are produced. But packaging is not carried out in any of the strain because none of the strain is having full complement of proteins to carry out packaging.

13. Chain-termination mutations in coat proteins genes are carried out. The coat protein coat genes used are __________
a) A gene
b) D gene
c) E and D gene
d) D and A gene
Answer: c
Explanation: Chain-termination mutations in coat proteins genes are carried out, these genes are D and E genes.

300+ TOP MCQs on Removal and Introduction of Restriction Sites and Generation of Insertions and Deletions and Answers

Genetic Engineering Question Bank focuses on “Removal and Introduction of Restriction Sites and Generation of Insertions and Deletions”.

1. Direct alteration of particular parts of protein as a way of probing the relationship between structure and function is termed as:
a) genetic engineering
b) protein engineering
c) alteration of protein function
d) structure engineering
Answer: b
Explanation: Protein engineering is the direct alteration of parts of protein as a way of probing the relationship between its structure and function. The function of protein is altered in a controlled way.

2. At times, the gene which is cloned is not well known for the protein encoded by it. To access the function, the endogenous gene for the mutant strain is inactivated. This technique is called as ___________
a) reverse genetics
b) protein engineering
c) mutation
d) location of function
Answer: a
Explanation: Reverse genetics is the technique by which the exact function of the gene cloned is known. It is done by inactivating the mutant strain in the host.

3. Approaches for creating mutations can be divided into how many types?
a) 1
b) 2
c) 3
d) 4
Answer: b
Explanation: There are basically two approaches to creating mutations. They are relying on restriction enzymes and oligonucleotide-directed DNA synthesis.

4. In the case of deletion of a restriction site, it should be cleaved with the same restriction enzyme.
a) True
b) False
Answer: a
Explanation: For the deletion of a restriction site, it should be cleaved with the same restriction enzyme. As it is cleaved, the restriction site is destroyed and further the staggered ends created are either filled or degraded. After this religation is carried out but the restriction site is destroyed.

5. If there are multiple restriction sites for an enzyme in a given molecule, digestion is carried out in many steps. The initial digestion should be?
a) complete
b) partial
c) carried out by a different enzyme then that the restriction site
d) carried out by a mixture of restriction enzymes
Answer: b
Explanation: If there are multiple restriction sites for an enzyme in a given molecule, the initial digestion would be partial. It is so because molecules cut on one site at an average.

6. If a functional gene is disrupted while disrupting a restriction site _______ is created.
a) frameshift mutation
b) point mutation
c) either of the mutations
d) any other kind of mutation
Answer: a
Explanation: If a functional gene is disrupted while disrupting a restriction site, a frameshift mutation would be created. As it is created, the gene might become dysfunctional.

7. Additional restriction sites can be introduced near the existing restriction site by mutagenesis.
a) True
b) False
Answer: a
Explanation: Additional restriction sites can be introduced near the existing restriction site by mutagenesis. It is done by inserting chemically synthesized oilgonucleotide carrying the appropriate sequence.

8. Restriction site can also be introduced by oligonucleotide directed mutagenesis of a region that is _______ and ______ to the original restriction site.
a) not only similar, also exactly same
b) similar, not same
c) not similar, is entirely different
d) different, near
Answer: b
Explanation: Restriction site can also be introduced by oligonucleotide directed mutagenesis of a region that is similar and is not the same to the original restriction site.

9. Small deletions at a restriction site can be generated by cutting and degrading the ________ with an exonuclease.
a) double stranded ended
b) circular molecules
c) single stranded ends
d) supercoiled molecules
Answer: c
Explanation: Small deletions at a restriction site can be generated by cutting and degrading the single stranded ends with an exonuclease.

10. When a series of deleted regions are replaced by some other DNA fragment of equal length, then it is known as:
a) linker scanning
b) generation of deletions
c) mutation
d) replacement
Answer: a
Explanation: Sometimes, a series of deleted regions are replaced by a fragment of DNA of equal length, then it is called as linker scanning. It is done in order to not disrupt the spacing between control regions.

250+ TOP MCQs on Protein Structural Visualization and Answers

Bioinformatics Multiple Choice Questions on “Protein Structural Visualization”.

1. The main feature of computer visualization programs is interactivity, which allows users to visually manipulate the structural images through a graphical user interface.
A. True
B. False

Answer: A
Explanation: At the touch of a mouse button, a user can move, rotate, and zoom an atomic model on a computer screen in real time, or examine any portion of the structure in great detail, as well as draw it in various forms in different colors. Further manipulations can include changing the conformation of a structure by protein modeling or matching a ligand to an enzyme active site through docking exercises.

2. A Protein Data Bank (PDB. data file for a protein structure contains only x, and z coordinates of atoms.
A. True
B. False

Answer: B
Explanation: Because a Protein Data Bank (PDB. data file for a protein structure contains only x, y, and z coordinates of atoms, the most basic requirement for a visualization program is to build connectivity between atoms to make a view of a molecule. The visualization program should also be able to produce molecular structures in different styles, which include wire frames, balls and sticks, space-filling spheres, and ribbons.

3. A wire-frame diagram is a line drawing representing bonds between atoms.
A. True
B. False

Answer: A
Explanation: The wire frame is the simplest form of model representation. It is useful for localizing positions of specific residues in a protein structure, or for displaying a skeletal form of a structure when Cα atoms of each residue are connected.

4. Balls and sticks are solid spheres and rods, representing atoms and bonds, respectively.
A. True
B. False

Answer: A
Explanation: These diagrams can also be used to represent the backbone of a structure. In a space-filling representation, each atom is described using large solid spheres with radii corresponding to the van der Waals radii of the atoms.

5. Ribbon diagrams use cylinders or spiral ribbons to represent α-helices and broad, flat arrows to represent β-strands.
A. True
B. False

Answer: A
Explanation: This type of representation is very attractive in that it allows easy identification of secondary structure elements and gives a clear view of the overall topology of the structure. The resulting images are also visually appealing.

6. Different representation styles can be used in combination to highlight a certain feature of a structure while deemphasizing the structures surrounding it.
A. True
B. False

Answer: A
Explanation: For example, a cofactor of an enzyme can be shown as space-filling spheres while the rest of the protein structure is shown as wire frames or ribbons. Some widely used and freely available software programs are there for molecular graphics.

7. Which of the following is wrong about Swiss-PDB Viewer?
A. It is a structure viewer for multiple platforms
B. It is a structure viewer for single platforms
C. It is essentially a Swiss-Army knife for structure visualization and modeling
D. It is capable of structure visualization, analysis, and homology modeling

Answer: B
Explanation: It is essentially a Swiss-Army knife for structure visualization and modeling because it incorporates so many functions in a small shareware program. It allows display of multiple structures at the same time in different styles, by charge distribution, or by surface accessibility. It can measure distances, angles, and even mutate residues. In addition, it can calculate molecular surface, electrostatic potential, Ramachandran plot, and so on. The homology modeling part includes energy minimization and loop modeling.

8. Which of the following is an incorrect statement?
A. WebMol is a web-based program built based on a modified RasMol code and thus shares many similarities with RasMol
B. WebMol is a web-based program that is totally different from RasMol
C. Chime is a plug-in for web browsers
D. Chime is not a standalone program and has to be invoked in a web browser

Answer: B
Explanation: Chime is also derived from RasMol and allows interactive display of graphics of protein structures inside a web browser. RasMol runs directly on a browser of any type as an applet and is able to display simple line drawing models of protein structures. It also has a feature of interactively displaying Ramachandran plots for structure model evaluation.

9. Which of the following is an incorrect statement?
A. Molscript is a UNIX program capable of generating wire-frame
B. Molscript is capable of generating space-filling
C. Molscript is not capable of generating ball-and-stick styles
D. In particular, secondary structure elements can be drawn with solid spirals and arrows representing α-helices and β-strands, respectively

Answer: c
Explanation: Visually appealing images can be generated that are of publication quality. The drawback is that the program is command-line–based and not very user friendly. A modified UNIX program called Bobscript is available with enhanced features.

10. Ribbons another UNIX program similar to Molscript, generates ribbon diagrams depicting protein secondary structures.
A. True
B. False

Answer: A
Explanation: Aesthetically appealing images can be produced that are of publication quality. However, the program, which is also command-line-based, is extremely difficult to use.
