Question

The RNA polymerase holoenzyme transcribes:

Answer 1

Transcription unit:

Transcription unit is the segment of DNA taking part in the transcription. It consists of promoter, structural gene and terminator.


Promoter:

Promoter is the DNA sequence where the sigma factor binds to initiate transcription. However, the promoter region is not transcribed by the RNA polymerase.

Structural gene:

The structural gene is the DNA sequence that is transcribed by the RNA polymerase holoenzyme. It contains the information for the synthesis of a polypeptide.


Terminator:

Terminator site is the DNA sequence where the transcription process is terminated

Final answer: d. the structural gene only
