Unformatted text preview: snap + easily meltable U-A H bonds = rip RNA off of DNA 6. RNA Polymerase dissociates after a) rho helps to dissociate b) loosing RNA Eukaryotes no NusA, no factor, more variation [substitution of conserved sequences] Initiation 1. Promoter site - 1) binding site for RNA polymerase [GC & CAAT boxes - TFs], 2) site for unwinding [-25 TATA box], 3) mark exact start point [+1 - A] 2. Transcription Factors [TFs] binds to promoter site at specific conserved sequences each RNA P has a set of TFs 3. RNA Polymerase recognizes/binds to complex of TFs [big complex of TFs & RNA P cover entire promoter Elongation [3 different RNA Polymerases specific to RNA] no NusA 4. RNA Polymerase RNA P I [rRNA except 5s], RNA P II [mRNA], RNA P III [small RNAs tRNA, 5s rRNA] transcribes certain set of genes [3 RNA Ps 3 different categories of promoter] Termination 5. Different for each RNA Polymerase...
