BIO 198 Chapter Notes - Chapter 9: Elongation Factor, Metabolic Pathway, Eukaryotic Initiation Factor 3
Document Summary
9. 1 polypeptides are aa chains formed in ribosomes. There are twenty aa that have similar backbone structures but a different r group. 9. 2 translation occurs in three phases (311-319) Initiator factors proteins (if) help control ribosome formation and binding of the initator trna: charged trnas trnas carrying a specific aa, uncharged trnas trnas that are without an aa. Bacterial translation initiation six critical units (mrna, the small. Shine-salgarno sequence a sequence between the 16srrna the. If3 facilitates binding between the mrna and the small subunit subunit, the large subunit, the initiator trna, three ifs, and gtp) and prevents the small subunit from binding to the large subunit. Preinitiation complex (bacteria) the complex formed when the authentic start codon sequence is identified by base pairing that occurs in. If2 and gtp bind to the p state and facilitate the binding of.
