BIOXII06: MOLECULAR BASIS OF INHERITANCE
343312
Which of the following steps in transcription is catalysed by RNA polymerase?
1 Initiation
2 Elongation
3 Termination
4 All of these
Explanation:
The RNA polymerase is only capable of catalysing the process of elongation.

343313
In bacteria, transcription and translation takes place in the same compartment. Why?
1 No separation of cytosol and nucleus
2 mRNA does not require any processing to become active
3 Both (1) and (2)
4 Transcription occurs in different compartments
Explanation:
In bacteria, transcription and translation take place in the same compartment, there is no separation of cytosol and nucleus in bacteria.

RNA polymerase III helps in transcription of
1 t-RNA
2 r-RNA
3 sn-RNA
4 1 and 3
Explanation:
RNA polymerase III is responsible for transcription of tRNA, 5srRNA, and snRNAs (small nuclear RNAs)

Statement A : hnRNA is larger than mRNA. Statement B : hnRNA is made up of exons and introns.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Premature mRNA consists of the bulk of hnRNA and includes nuclear RNA transcripts which do not end up as cytoplasmic mRNA. The hnRNA contains both the introns and exons, but, the mRNA contians only the exons.
