Riboswitch is a mechanism of gene activity regulation by mRNA conformation. Riboswitch can regulate ______.
Select one:
a. transcription
b. translation
c. both transcription and translation
d. neither transcription nor translation
Homework Answers
Answer c. both transcription and translation
Riboswitch regulates the gene expression. They are RNA elements and they binds with small molecules. Hence they can know about the intracellular concentration of those molecules. The ribo switch regulates its adjacent genes by altering its transcription and translation
