Question

Which of the following is used to describe the time taken by RNA polymerase to leave the promoter?

• A. Promoter clearance time
• B. Abortive initiation
• C. Elongation factor
• D. Mean time

Answer 1

Answer:

A. Promoter clearance time

Promoter clearance time is the time taken by RNA polymerase core enzyme to leave the promoter. More the efficient promoter sequences, lesser would be the promoter clearance time.
