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...

How does translation terminate? - ️️-stop codon (UAA, UAG,UGA) -instead of tRNA, release factor binds to ribosome, causing hydrolysis of the peptidyl tRNA, releasing the completed protein -ribosome dissociates into its subunits, releasing mRNA, release factor, and tRNA mRNA and protein synthesis are very energetically - ️️adding each subunit requires the conversion of an NTP to an NMP, equivalent to hydrolyzing 2 ATPS to ADP -elongation step consume multiple ATP/GTP -splicing and ...
