As Transcription Begins,RNA Polymerase Binds to a Segment of a Gene

Question

As transcription begins,RNA polymerase binds to a segment of a gene called a(n)
A) promoter.
B) intron.
C) start codon.
D) anticodon.

Accepted Answer

RNA polymerase binds to a segment of a gene called a promoter in order to initiate transcription. The promoter region typically includes the start site for transcription and contains specific DNA sequences that help to recruit RNA polymerase to initiate transcription. The other options listed (intron, start codon, and anticodon) are all involved in different stages of protein synthesis, but not in the initiation of transcription specifically.
