Question

In general, repressor proteins that act to inhibit eukaryotic gene expression:

Answer 1

A protein in which its binding to the operator inhibits the transcription of one or more genes. Supplement. Repressor proteins can be DNA– or RNA-binding: DNA-binding repressors – block the binding of RNA polymerase to the promoter. As a result, the gene is prevented from being transcribed into mRNA. Most eukaryotic repressors also are modular proteins. Similar to activators, they usually contain a single DNA- binding domain, one or a few repression domains, and can control transcription when they are bound at sites hundreds to thousands of base pairs from a start site.
