Question

Autoregulation occurs when ــــــــــــــــــــ.
A)IPTG binds to LacI
B)allo-lactose binds to LacI
C)a repressor binds to its own gene to prevent transcription
D)CRP binds to cAMP and the the lac operon

Accepted Answer

Autoregulation occurs when a gene product (often a protein) regulates its own production by binding to its own gene's regulatory sequences, thereby influencing the transcription of its own mRNA. This is a form of negative feedback where a repressor protein can bind to the promoter or operator region of its own gene, reducing its own synthesis by preventing transcription.
