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.
