In prokaryotic cells, repressor proteins bind to a section of DNA called a/an(1 point) Responses chromatin. chromatin. repressor. repressor. operator. operator. promoter.

Answer 1

The correct answer is "operator." The operator is a section of DNA located near the promoter region to which repressor proteins can bind. This binding prevents RNA polymerase from transcribing the genes in that region, effectively turning off gene expression.
