Document Summary

Bsc2010:integrative principles of biology-lecture #8: genetic code, translation(protein. Mrna triplets (codons) from 5" to 3" Polypeptide synthesized from amino to carboxyl ends. Stop codons- { 5" uag 3" } {5" uga 3"}{5" uaa 3"} Multiple codons for the same amino acids whereas unambiguous= each codon specifies one amino acid. Codon has three positions because it"s a triplet (1st 2nd 3rd); most redundancy occurs at the 3" end. Ribosomes: half ribosomal protein, ribosomal rna; polypeptide synthesis is catalysts by the rrna and not the ribosomal proteins. Trna to codon 3" to 5 and u to 5" to 3" a.
