Molecular Biology Help The core promoter element of RNA poly

Molecular Biology Help!

The core promoter element of RNA polymerase II extends from about 40 bp upstream of the transcription initiation site to about _______ bp downstream from this site.

RNA polymerase II requires the assistance of general ________________ to transcribe naked DNA from specific transcription sites.

Pre-initiation begins with either _________ or TATA binding protein binding to the core promoter.

The C-terminal domain of the largest RNA polymerase subunit must be ____________ for chain elongation to occur.

Solution

Ans A 40

The core promoter element of RNA polymerase II extends approx 40 bp up and 40 bp down stream of the start site of transcription and it contains several other core promoter sequence elements.
