Document Summary
Lecture 5: bio 97 trna: there is a gene for transfer rna. Uac which will base pair with aug: anticodon base pairs with codon. Side chain (r): is what gives it diversity. This all is determined by the side chain. Joins amino acids: amino group makes a bond with a carboxyl group. Translation can be divided into three pahses: initiation: translation machinary gures out where it should start elongation: adds more subunits termination: stops and reads/signals this is where the protein should be truncated. The phases are similar in bacteria and eukaryotes, though there are several differences. Trna is present at the p site: the initiating methionine trna is in the p (peptide) site. Carboxyl group on lysine with amino group of arg. *basic concept= where amino / carboxyl group comes from and how we form a bond. No trna for stop codon, release factor binds instead. The portion of the mrna after the stop codon is the 3 utr.
