What are elongation factors? (transcription) - ️️use ATP hydrolysis to help RNA poly. move along chromatin -make sure RNA isnt falling off DNA/ skipping nucleotides Differences between eukaryotic and prokaryotic transcription - ️️- Euk: Have 3 different RNA polymerases. Pro: only one - Starting --- Euk: Needs general transcription factors to start transcription and position RNA polymerase. Pro: RNA polymerase binds to promoter sequence immediately. - Stopping --- Euk: Polyadenylat...
