The Regulatory Protein

Question

The regulatory protein
A)binds to the promoter region of DNA.
B)may inhibit or enhance transcription.
C)may control translation of the operon.
D)affects the activity of the DNA polymerase.
E)binds to the promoter region of DNA AND affects the activity of the DNA polymerase.

Accepted Answer

The regulatory protein can either inhibit or enhance transcription by binding to the operator region of DNA. It does not affect the activity of DNA polymerase, and it does not control translation of the operon. While some regulatory proteins can bind to the promoter region of DNA, not all do.
