| A molecule to act as a genetic material has the following properties |
| I. should be able to replicate. |
| II. should be structurally more stable. |
| III. should be more reactive and labile. |
| IV. should provide scope for slow changes. |
| Choose the correct option. |
A) I, II and III are correct
B) III alone is correct
C) III and IV are correct

Solution :
[d] A molecule to act as a genetic material must fullfil the following criteria It should be able to replicate or form its carbon copies. Genetic material should be able to express itself through formation of specific biochemicals. There are occasional changes or mutations in the structure and functioning of its genes which are of permanent nature and inheritable. Mutations are essential for evolution and adaptability. It should be stable both chemically and physically. Thus, statement III is incorrect, while other three are correct.
