Which of the following criteria must a molecule fulfil to act as a genetic material?
(I) It should not be able to generate its replica
(II) It should chemically and structurally be stable
(III) It should not allow slow mutation
(IV) It should be able to express itself in the form of Mendelian Characters

A

(I) and (II)

B

(II) and (III)

C

(III) and (IV)

D

(II) and (V)

Text Solution

Verified by Experts

The correct Answer is:
D
The molecule should be able to undergo replication. Expressing itself in the form of Mendelian characters is also necessary. It will be able to act as the perfect genetic material only when its chemically and structurally stable. DNA fulfils all these criteria.
