| 1. | Operator | 2. | Promoter |
| 3. | Structural gene | 4. | Terminator |
DNA-dependent RNA polymerase catalyzes polymerization in:
| 1. | Only in 3’ – 5’ direction |
| 2. | Only in 5’ – 3’ direction |
| 3. | In both directions |
| 4. | In neither directions |
Which of the following helps in the termination of transcription?
| 1. | Sigma factor | 2. | Translocase |
| 3. | Ubiquitin | 4. | Rho factor |
Transcription and translation can be coupled in:
| 1. | Bacteria | 2. | Yeast |
| 3. | Plants | 4. | Animals |
| 1. | siRNA | 2. | miRNA |
| 3. | hnRNA | 4. | dsRNA |
| Assertion (A): | Both strands of DNA are not transcribed. |
| Reason (R): | Transcribing both strands would create complementary RNA molecules that would bind to each other and interfere with normal cell processes. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
