Question

in prokaryotic cells, repressor proteins bind to a section of dna called a/an (1 point)
repressor
promotor
chromatin
operator

Explanation:

In prokaryotic cells, the repressor protein binds to the operator region of DNA. The operator is a specific DNA sequence that controls the access of RNA polymerase to the promoter. When the repressor binds to the operator, it blocks the transcription of genes in the operon. The promoter is where RNA polymerase binds to initiate transcription. Chromatin is a complex of DNA and proteins in eukaryotic cells. The repressor is the protein itself, not the DNA section it binds to.

Answer:

Operator
