Question

Which of the following is the correct statement about the process of transcription?

A.

Sequence of nucleotides in transcribed RNA is similar to coding strand of DNA

B.

Helicase and topoisomerase enzymes help in unwinding of DNA double helix during transcription

C.

RNA polymerase enzyme becomes holoenzyme when rho-factor attaches with core enzyme

D.

Promoter is present just at the site from where RNA transcription begins and the portion of DNA present in promoter is also transcribed

Correct option is A

Correct Answer: (a)
Explanation:
RNA sequence is complementary to template strand and is almost identical to coding strand, except U replaces T.
Information Booster:
Only one strand of DNA is transcribed.
RNA polymerase synthesizes RNA 5’→3’.
Coding strand resembles the RNA sequence.
Template strand guides nucleotide arrangement.
Promoter region is not transcribed.
Additional Information (Incorrect Options):
(b) RNA polymerase itself unwinds DNA during transcription.
(c) Rho-factor is involved in transcription termination, not holoenzyme formation.
(d) Promoter is not transcribed; it only signals start point.
