Text Solution

Verified by Experts

The correct Answer is:
A
`**" "`There are at least three RNA polymerases in the nucleus (in addition to the RNA polymerase found in the organelles).
`**" "`There is a clear cut division of labour.
`**" "`The RNA polymerase I transcribes rRNAs (28S, 18S and 5.8S).
`**" "`The RNA polymerase II transcribes precursor of mRNA, the heterogeneous nuclear RNA (hn RNA).
`**" "`RNA polymerase III is responsible for transcription of tRNA, 5srRNA, and snRNAs (small nuclear RNAs).
