A2 Biology - transcription factors and gibberellin

A2 Biology - Inheritance topic - What are transcription factors and how do they initiate transcription? Description of how gibberellin interacts with the DELLA repressor protein to allow the PIF transcription factor to bind and allow amylase to be produced.

Thank you I'm doing a presentation on this and have no idea what it was

I'm a bit confused. So does this mean that RNA Polymerase have to join with PIF and then move along with the PIF to do transcritpiton. Or does it mean that PIF helps RNA polymerase like a missing piece for RNA to combine to the promoter and then there after RNA polymerase alone will move to read the genes for transcription?

Thanks miss, , but ur sound is really low:((
