Which of the following levels of regulation of gene expression is predominant in prokaryotes?
Which of the following levels of regulation of gene expression is predominant in prokaryotes?
Translational level
Processing level
Transport level
Transcriptional level
Solution
In prokaryotes, control of the rate of transcriptional initiation is the predominant site for control of gene expression. The activity of RNA polymerase at a given promoter is regulated by interaction with accessory proteins, which affect its ability to recognise start sites.
