Control of gene experssion takes place at the level of

A

DNA-replication

B

transcription

C

translation

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
Considering that gane expression results in the formation of a polypeptide, it can be regulated at several levels. In eukaryotes, the regulation could be exerted at
(i) transcription leval (formation of primary transcrpt )
(ii) processing leval (regulation of splicing )
(iii) transport of mRNA from nucleus to the cytoplasm
(iv) translational level
While, in prokaryotes, control of the rate of transcriptional initiation is the predominant site for control of gene expression.
