In fact, it even goes by the name 'Universal Genetic Code.' One example would be ACG coding for the amino acid threonine (Thr) in humans, cats, and plants. WebThe start codon sets the reading frame: instead of continuing to move down the mRNA transcript one base at a time, the ribosome now reads the mRNA codons consecutively, three bases at a time (Fig. 3.18).The sequence of the triplet codon determines which amino acid is added next to the growing protein.
