b. Elongation, ribosome-binding, and termination.
c. Initiation, elongation, and termination.
d. Initiation, regulation, termination.

Q2. Sigma factor (σ) is needed during which stage(s) of transcription?

a. Initiation                                                              b. Elongation

c. Termination                                                        d. All of the above

Q3. With regard to a promoter, a transcriptional start site is
a. located at the –35 position and recognized by σ factor.
b. located at the –35 position and is where the first base is used as a template for RNA transcription.
c. located at the +1 position and recognized by σ factor.
