Explanation / Answer

Option 1, 3,5 are correct

Explanation:

Binding of the sigma factor to the RNA enzyme core catalyst forms the RNA enzyme holoenzyme. solely the holoenzyme binds to the promoter. while not the sigma issue, RNA enzyme is going to be unable to bind the promoter and transcription initiation won't occur. Any RNA enzyme that has completed transcription initiation and has begun elongation can complete transcription as a result of the sigma issue isn't required for elongation. However, no any initiation are going to be potential at the elevated temperature.
