Peptide Chain Elongation

3 stop codons indicate the end of the protein (UAG, UAA, UGA) and 1 start codon indicates the beginning of the protein (AUG). The code is degenerate = more ... In molecular biology, a stop codon (or termination codon) is a codon that signals the termination of the translation process of the current protein. Nov 22, 2023 ... The stop codon is the last three bases of the coding sequence, not of the exon per transcript, as there are untranslated exons (5'- and 3 ... Nov 3, 2023 ...
