Question 3
1 / -0

Following question consists of two statements, one labelled as 'Assertion A' and the other labelled as 'Reason R'. You are to examine these statements carefully and decide if the Assertion (A) and the Reason (R) are individually true and if so, whether the Reason is a correct explanation for Assertion. Select your answer from the codes given below.

(A) : DNA ligase is used as a fusogenic agent in protoplasmic fusion technology.
(R) : Fusogenic agent will promote the fusion of protoplasts.

A
Both (A) and (R) are true and (R) is the correct explanation of (A).

B
Both (A) and (R) are true and (R) is not the correct explanation of (A).

C
(A) is true, but (R) is false.

D
(A) is false, but (R) is true.
Question 4
1 / -0

Consider the following statements:

(1) BT cotton is a hybrid plant.
(2) National Research Centre on Plant Biotechnology is located in New Delhi.

Which of the given statements is/are correct?

A
Only (1)

B
Only (2)

C
Both (1) and (2)

D
Neither (1) nor (2)
Question 5
1 / -0

Brief exposure of cells to an electric field also allow the bacteria to take up DNA and this process is called as

A
Electroporation

B
Electrolysis

C
Electrophoresis

D
Apheresis

Solution

Electroporation, or electropermeabilization, is a microbiology technique in which an electrical field is applied to cells in order to increase the permeability of the cell membrane, allowing chemicals, drugs, or DNA to be introduced into the cell
Question 6
1 / -0

A radioisotope used to label proteins differently from nucleic acids is

A
14C

B
15N

C
32P

D
35S
Question 7
1 / -0

Hypervariables are useful in

A
DNA fingerprinting

B
genetic engineering

C
cloning

D
gene sharing
Question 8
1 / -0

The mass of undifferentiated cells is called

A
callus

B
explant

C
suspension culture

D
leaven
Question 9
1 / -0

A transgene can

A
prevent the expression of a native gene

B
modify an existing biosynthetic pathway

C
produce a protein that itself produces a phenotype of interest

D
All of the above
Question 10
1 / -0

Host cell membrane can be made permeable by

A
Zinc

B
CaCl₂

C
Ammonium Carbonate

D
Tollen’s reagent

Solution

CaCl₂ can be used to make the bacterial cell a permeable cell, and by introducing these cells (after CaCl₂ being placed into the mixture of bacterial cells), a plasmid for ampicillin resistance can be transformed into the bacteria. The standard method for making the bacteria permeable to DNA involves treatment with calcium ions
