Question

Explain how the repressor molecule would stop a gene from being expressed.

Answer 1

A repressor blocks the attachment of RNA polymerase, the formation of DNA, and stops the transcription of genes.

Step-by-step explanation:

Answer 2

The repressor molecule is a DNA or RNA binding protein. A DNA-binding repressor blocks the attachment of RNA polymerase, the enzyme that brings the formation of DNA and RNA, to the promoter, and prevents the transcription of genes into messenger RNA.
