The Regulatory Activity of SRNA

Question

The regulatory activity of sRNA
A) codes for a sigma factor.
B) prevents CRP interaction with RNA polymerase, thereby blocking its access to the promoter.
C) synthesizes ppGpp.
D) targets mRNAs for degradation.
E) creates an attenuator stem loop.

Accepted Answer

sRNA can regulate gene expression by binding to specific mRNA targets, resulting in degradation of the mRNA by RNase E or blocking translation initiation. This activity of targeting mRNAs for degradation is a common regulatory mechanism of sRNA.
