Question

During transcription, RNA polymerase holoenzyme binds to gene promoter and assumes a saddle-like structure. The DNA binding sequence is ______.

विकल्प

• AATT

• TTAA

• TATA

• CACC

Answer 1

During transcription, RNA polymerase holoenzyme binds to gene promoter and assumes a saddle-like structure. The DNA binding sequence is TATА.

Explanation:

The promoter includes a TATA-rich DNA sequence recognised during transcription initiation. The other sequences are not the promoter sequence identified here.
