RNA polymerase binds to promoter but cannot initiate transcription T/F
A
True
B
False
Answer
True
Explanation
Solution
RNA polymerase initially binds to the promoter forming a closed complex. However, it cannot initiate transcription until it undergoes conformational changes (isomerization) to form an open complex, where the DNA strands are unwound for transcription to begin.
