| Assertion (A): | tRNA is the adapter molecule in the flow of genetic information in a typical cell. |
| Reason (R): | tRNA has some unusual bases present in the sequence of its nucleotides. |
| 1. | Both (A) and (R) are True and (R) correctly explains (A) |
| 2. | Both (A) and (R) are True but (R) does not correctly explain (A) |
| 3. | (A) is True, (R) is False |
| 4. | (A) is False, (R) is True |
| 1. | Smaller subunit of bacterial ribosome |
| 2. | Larger subunit of bacterial ribosome |
| 3. | Smaller subunit of eukaryotic ribosome |
| 4. | Larger subunit of eukaryotic ribosome |
| Assertion (A): | In the first phase of translation itself, amino acids are activated in the presence of ATP. |
| Reason (R): | If two such charged tRNAs are brought close enough, the formation of peptide bond between them would be favoured energetically. |
