Document Summary

This is because 1 codon corresponds to 1 amino acid, but 1 amino acid may come from diferent possible codon. Cuc, cua, cug all codes for leucine: codon the combinaion of 3 nucleoides codes for one speciic amino acid. For example, ccu codes for proline. (special codons: uaa/uag/uga stop codon; aug methionine/start codon) Decoding process: mrna (message rna) is a copy of geneic informaion (base sequence) from. Pepide bonds are formed between the amino acids. Promoter (where transcripion starts: the three-frame problem: the shiting/changing when reading the three- nucleoide-codon leads to diferent amino acids. Pepides formed between amino acids: ribosome shit 1 codon upstream, 1st trna leaves ribosome, 2nd trna moves to p site. A site empies, ready for the next trna: terminaion: when ribosome reaches the stop codon, a release factor comes in instead of trna. Small subunit and large subunit of ribosome separate.
