A) Initiation; A - DNA, B - RNA, C - Promoter
B) Termination; A - RNA, B - RNA polymerase, C - Rho factor
C) Elongation; A - RNA, B - RNA polymerase, C - Sigma factor
D) Elongation; A-DNA, B - DNA polymerase, C - RNA
Correct Answer: B
Solution :
[b] In the given figure, the step shown is termination of transcription in bacteria. The label A, B and C are respectively KNA, RNA polymerase and rho factor. RNA polymerase is an enzyme that synthesizes the formation of RNA from a DNA. Template during transcription. Rho factor is a termination factor which releases RNA from the DNA template.
