genetic code

n.
1. The set of DNA and RNA sequences that determine the amino acid sequences used in the synthesis of an organism's proteins. It is the biochemical basis of heredity and nearly universal in all organisms.
2. The set of 64 codons corresponding to the 20 amino acids used for protein synthesis and as the signals for starting and stopping protein synthesis.

genetic coding n.

genetic code

n
(Biochemistry) biochem the order in which the nitrogenous bases of DNA are arranged in the molecule, which determines the type and amount of protein synthesized in the cell. The four bases are arranged in groups of three in a specific order, each group acting as a unit (codon), which specifies a particular amino acid. See also messenger RNA, transfer RNA

genet′ic code′


n.
the biochemical instructions that translate the genetic information present as a linear sequence of nucleotide triplets in messenger RNA into the correct linear sequence of amino acids for the synthesis of a particular peptide chain or protein. Compare codon, translation (def. 6).
[1960–65]

ge·net·ic code

(jə-nĕt′ĭk)
The sequence of organic bases (called nucleotides) in DNA and RNA that determines the structure of amino acids in a protein.

The scientists' altered tRNA, however, reads the amber codon as if it were glutamine and adds that amino acid, enabling the protein to grow to its normal length.
