Without the sigma factor, what will happen?

Without the sigma factor, what will happen? RNA polymerase won\'t be able to bind to the -35 regions. RNA polymerase won\'t be able to bind to the -10 regions. DNA polymerase won\'t be able to bind to the -35 regions. DNA polymerase won\'t be able to bind to the -10 regions.

Solution

Answer : The correct answer is B ( RNA polymerase won\'t be able to bind to the -10 region)

Explanation : Sigma subunit plays an important role in directing the RNA polymerase to bind to specific sites on DNA molecules called promoters and also reduces the affinity of RNA Polymerase for non specific sites on DNA during transcription.
