The genetic code is the set of rules used by living cells to translate information encoded within genetic material (DNA or RNA sequences of nucleotide triplets, or codons) into proteins. Translation is accomplished by the ribosome, which links proteinogenic amino acids in an order specified by messenger RNA (mRNA), using transfer RNA (tRNA) molecules to carry amino acids and to read the m… WebSep 15, 2024 · Genetic code and codon are two methods used to store genetic information in the genetic material.

WebThe genetic codes are degenerate because an amino acid is not always coded from a specific codon. Some amino acids can be coded from multiple codons. Missense codons code for incorrect amino acids or act as stop codons. Nonsense amino acids act as stop codons and terminate the translation process prematurely. WebMay 23, 2024 · In this way the genetic code is said to be degenerate, meaning that each of the 64 possible triplets have some meaning within the code and that several codons may encode a single amino acid.
