Code
The genetic code is the correspondence between the triplet of bases in dna with the amino acids. The discovery of the genetic code clearly ranks as one of the premiere events of what has been called the golden age of biology (and Medicine).

A code in which several code words have the same meaning. The genetic code is degenerate because there are many instances in which different codons specify the same amino acid.
The genetic code consists of 64 triplets of nucleotides. These triplets are called codons.With three exceptions, each codon encodes for one of the 20 amino acids used in the synthesis of proteins.

genetic code
The system of nucleotide triplets in DNA and RNA that carries genetic information; referred to as a code because it determines the amino acid sequence in the enzymes and other protein molecules synthesized by the organism.
Genetic code
The assignment of each of the triplet codons of mRNA to amino adds and translation stop signals. See Codon table.

The table below can be used to determine what amino acid corresponds to any 3-letter codon.

Genetic code. The three-letter code that translates nucleic acid sequence into protein sequence.
Genetic code The rules for converting the sequence of nucleotides in mRNA into a sequence of amino acids in a polypeptide.
The code consists of at least three bases, according to astronomer George Gamow. To code for the 20 essential amino acids a genetic code must consist of at least a 3-base set (triplet) of the 4 bases.
Genetic code
The sequence of nucleotides, coded in triplets (codons) along the mRNA, that determines the sequence of amino acids in protein synthesis.
Genetic code is the term we use for the way that the four bases of DNA--the A, C, G, and Ts--are strung together in a way that the cellular machinery, the ribosome, can read them and turn them into a protein.

The three letter code is the same for all organisms (with a few exceptions). There are 64 codons, but only 20 amino acids to code for; so, most amino acids are coded for by several codons.
Available name A name that is correctly proposed according to the International Code of Zoological Nomenclature. An available name is not necessarily the valid name.
Category Any rank within the classification hierarchy, e.g.
Degeneracy Backtranslation of amino acid sequences usually leads to a collection of possible base sequences which can code for the amino acid sequence, due to the degeneracy of the genetic code.
The sequence of amino acids in a protein and hence protein function are determined by the genetic code
Amplification An increase in the number of copies of a specific DNA fragment; can be in vivo or in vitro.
The origin of the single-letter code for the amino acids is of historical interest, and in fact, this story may help the student to learn the code.
Pax genes code for (DNA binding) transcription factors. The paired box refers to a particular conserved DNA sequence that is shared by the different members of the Pax gene family.
