BIO 325 (BIO325)

transcription factor any group of proteins that can regulate gene activity by increasing or decreasing the binding of RNA polymerase to the DNA molecule during transcription. Achieved by the ability to bind to DNA molecules RNA Transcription Sequence (7 steps) 1. RNA polymerase together with 1+ transcription factors binds to promoter DNA 2. RNA polymerase breaks H-bonds between complementary DNA nucleotides and creates transcription bubble which separates the two strands of the DNA helix 3....
