Quizplus · Accepted Answer

The promoter sequence is the binding site for RNA polymerase on the DNA molecule. It is the sequence of nucleotides that signals the start of a gene and helps the RNA polymerase to find the correct position on the DNA to start transcription. Structural genes are the genes that code for proteins, and repressor genes are the genes that code for proteins that bind to operator sites to inhibit transcription. The operator sequence is the binding site for repressor proteins, and the region between an operator and the first structural gene is the promoter region. Therefore, the correct answer is C, the promoter sequence.
