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

Question

Quizplus · Accepted Answer

RNA polymerase binds to the promoter region of a gene to initiate transcription. The other options listed are related to the process of translation, which occurs after transcription is complete. Intron is a noncoding region of DNA that is transcribed but is removed from the pre-mRNA during splicing. A start codon and anticodon are segments of RNA involved in translation.
