For a(n) repressible operon, transcription normally takes place, and it is turned off by a(n) active repressor.
<h3>What is repressible operon ?</h3>
An operon that is normally on but that can be turned off in the presence of a repressor molecule is referred to as repressible. The repressor binds to the operator in such a way that it prevents RNA polymerase from moving or attaching, which prevents transcription from starting.
<h3>What is active repressor?</h3>
A protein that prevents the expression of one or more genes is known as a repressor in the context of genomics. The repressor protein inhibits the synthesis of messenger RNA by attaching to the promoter region of the gene(s) (mRNA). The control of gene expression in cells requires repressor proteins.
