Question

lecule ligands. The mechanism of riboswitch regulation involves short ribonucleotide sequence elements that are capable of binding with small molecule ligands.
a) True
b) False

Answer 1

Answer:

a: True

Explanation:

Riboswitches are regulatory segments of mRNA which are capable of controlling/regulating gene expression simply by binding to small molecules. They are divided into two parts;

• The aptamer is the part that directly binds to small molecules
• The expression platform is the part that changes structure in response to  binding of aptamer to small molecules. This is the part that primarily controls gene expression by turning on/off relevant genes.

The correct option is a, true.
