Question

When a promoter element is bound by a positive regulatory protein, the result is?

Answer 1

When a promoter element is bound by a positive regulatory protein, the result is the activation of transcription. Transcription factors are protein that increase the transcription of genes or a single gene. Most of them are DNA-binding proteins that bind to enhancers or promoter-proximal elements. The factors may bind directly to a promoter regions of DNA , which normally lie upstream of the coding region in a gene, or onto the RNA polymerase molecule.
