Question

Transcription is terminated, when a characteristic RNA structure _____ is formed by local RNA palindromic sequences at the 3’- end. The structure interacts with RNAP-bound NusA, causing dissociation of RNAP from template DNA. The RNAP dissociation is stimulated by sequence-specific binding of _____ proteins to the transcribed RNA, enhancing termination of transcription.

Select one:

a. hairpin ;;;; rho

b. hairpin ;;;; sigma

c. beta-turn ;;;; rho

d. beta-turn ;;;; sigma

e. None of these

Answer 1

Option e is the correct answer none of these. because

The transcription process called as Rho dependent termination , it associates and binds to proteins .

At Rho independent termination ,the Rho protein is not associates to the hairpin formed .
