I. Proteins | II. DNA | III. RNA |
1. | Only I and II | 2. | Only I and III |
3. | Only II and III | 4. | I, II and III |
I: | are present at only the 5’ end of the mature mRNA in eukaryotes |
II: | are not required during translation and hence are spliced out of the mature mRNA |
1. | Only I is correct |
2. | Only II is correct |
3. | Both I and II are correct |
4. | Both I and II are incorrect |
I: | a polycistronic structural gene is regulated by a common promoter and regulatory genes |
II: | the regulation is always negative and inducible |
1. | Only I is correct |

Assertion (A): | VNTRs are the basis of DNA fingerprinting by RFLP |
Reason (R): | VNTRs are polymorphic and are inherited |
1. | Both (A) and (R) are True and the (R) is the correct explanation of the (A) |
2. | Both (A) and (R) are True but the (R) is not the correct explanation of the (A) |
3. | (A) is True but (R) is false |
4. | Both (A) and (R) are False |
I. | serve as substrate for DNA replication |
II. | provide energy for polymerisation reaction |
1. | Only I | 2. | Only II |
