During transcription, the DNA site at which RNA polymerase binds is called:

Options

  1. Apromoter
  2. Bregulator
  3. Creceptor
  4. Denhancer

Correct answer

A. promoter

Step-by-step solution

Promoter region is the proximal area of transcription unit, which provides site for attachment of transcription factors ( factor) and RNA polymerasc. It is present upstream at 5' end of coding strand. It has special structure; an AT rich area called TATA box or Pribnow box.
