give one difference between inducer and inhibitor gene?
Dear student
Please refer the solution below for the said query
Inducer is a molecule that activates gene expression i,e it regulates the switching on and off of the operon. It binds with the protein product of gene i (repressor protein) and inactivates it. For example, Lactose acts as an inducer for lac operon.
Inhibitory gene (i) is a regulatroy gene that codes for repressor protein of lac operon. In absence of inducer, i gene transcribes to synthesise repressor mRNA, which translates to form repressor. This repressor binds with the operator region of operon and prevents RNA polymerase to transcribe genes − z, y, and a (negative regulation). Thus preventing lactose metabolism.
Hope this information clears your doubt about the topic.
