Introduction to Biological Sciences 110a In class notes for November 9, 2007 We are covering two major processes: translation and transcription o Differences in bacteria and eukaryotes Transcription o To make a functional RNA there is a lot involved o Transcription-initiation, elongation, termination o Steps of transcription Template binding (by machinery that carries out process) Initiation Elongation Termination o On the slide, the yellow ball is RNA polymerase o So the main machinery involved in transcription is RNA polymerase o One form of RNA polymerase (primase) was used in DNA synthesis o The goal of the RNA we will use is to make a nucleotide correspond to a gene. o NTPs are the precursors So we have the same chemistry of the phosphoester bond as that of DNA synthesis. (3’ OH, pyrophosphate, 5’ P, etc) o The direction of synthesis of an RNA chain is 5’ to 3’ o In RNA synthesis you make a complementary copy of only one of the strands per transcription unit o To this point, everything we have said corresponds to both bacteria and eukaryotes
