The universality of the genetic code
WebSep 28, 2014 · The genetic code is contained in your DNA, and consists of 64 different three-letter ‘words’ (known as triplets or codons), 61 of which code for the 20 amino acids your body uses to make proteins, and three of which say ‘stop’. One codon codes both for an amino acid and for ‘start’. WebThe universal genetic code deviates slightly in mitochondria, where a few codons are translated in alternative ways. The most prevalent are methionine and tryptophan, which …

WebJan 25, 2024 · The universality of genetic code conveys that similar codons are assigned to identical amino acids, along with similar start and stop signals in the genes of most microorganisms and plants. Out of the few exceptions that were discovered, most of them include assigning one or two stop codons to an amino acid.
