Web30 dec. 2024 · The stop codons are sometimes also used to encode what are now considered the 21 st and 22 nd amino acids, selenocysteine (UGA) and pyrrolysine (UAG). These amino acids have been discovered to be consistently encoded in some species of prokarya and archaea. Note that there are no dedicated start codons: instead, AUG … WebIn translation codons of three nucleotides determine which amino acid will be added next in the growing protein chain. It is important then to decide which nucleotide to start translation, and when to stop, this is called an open reading frame. Once a gene has been sequenced it is important to determine the correct open reading frame (ORF). henleys towyn campsite
