Q. No.Consider the two statements:
| I. | In bacteria, translation initiation occurs as soon as the 5' end of an mRNA is synthesized, and translation and transcription are coupled. |
| II. | This is not possible in eukaryotes because transcription and translation are carried out in separate compartments of the cell |
| 1. | Both I and II are correct and II explains I |
| 2. | Both I and II are correct but II is not a correct explanation of I |
| 3. | I is correct and II is incorrect |
| 4. | I is incorrect and II is correct |
