Question

in what step of transcription does rna polymerase bind to the promoter on dna?
a initiation
b termination
c elongation

Explanation:

Transcription has three main steps. In the initiation step, RNA polymerase recognizes and binds to the promoter region on DNA. This binding is crucial as it starts the process of unwinding the DNA strands and preparing for RNA synthesis. The termination step is when the transcription process stops, and elongation is when the RNA strand is being lengthened. Since the question is about the binding to the promoter (which is the start - related event), initiation is the correct step.

Answer:

A. Initiation
