The "code" in which information for the synthesis of proteins is contained in the nucleotide sequence of a DNA molecule (or in certain viruses of an RNA molecule).

The nucleic acids, DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are the molecular substances in the cell nucleus, that are carriers of genetic information and are thus the basic genetic material in all living things. DNA occurs in the form of a double helix which acts as a template to reproduce itself. RNA is concerned with carrying the genetic information to the cytoplasm of the cell and establishing the genetic specifications there. Each of the various DNA assemblies can be called a gene.

a sequence of bases along a DNA (or RNA) molecule that determines the sequence of amino acids in the protein chain.

The sequence of bases on DNA, a functional unit of which is called a gene.

a system which describes how nucleotide sequences in DNA and amino acid sequences in proteins relate to each other.

The way in which information is carried by the DNA molecules determines the arrangement of amino acids in the proteins synthesized by the cells. Each of the 20 amino acids found in proteins is represented by 1 or more units of 3 consecutive nucleotide bases in the mRNA and in the DNA from which the mRNA is derived. All living organisms and viruses use the same genetic code.

The instructions in a gene that tell the cell how to make a specific protein. A, T, C, and G are the “letters” of the genetic code; they stand for the chemicals adenine, thymine, cytosine, and guanine, which make up DNA. Each gene's code combines the four chemicals in various ways, spelling out three-letter “words” that specify which amino acid is needed at every step in making a protein.

the standard code is shown in the table. Each sequence of three nucleotides in DNA or RNA potentially specifies an amino acid. In RNA, all T (thymidine) bases are replaced by U (uracil). Other than this, the DNA and RNA codes are the same. During translation, ribosomes and associated enzymes "read" mRNA containing the code and assemble chains of amino acids (i.e. proteins) according to this blueprint. The code is redundant, in that each amino acid (except tryptophan and methionine) is specified by more than one series of codons (nucleotide bases). The sequences UAA, UAG, and UGA signal the ribosome to terminate translation. There are minor variations in the code among eukaryotes. One of these is discussed in connection with the oxymonad Streblomastix. However, exceptions to the standard code are very rare.

The correspondence between the nucleotide sequences of gene molecules and the amino acid sequences of the protein gene product.

Each amino acid building block of a protein is specified by the order of nucleotides (A,C,T and G) in the gene for that protein.  Three adjacent nucleotides, called a codon, are required to specify one amino acid.  The genetic code can be displayed in a table that translates each of the 64 possible triplet codons into an amino acid.  There are 64 possible combinations resulting from having one of four nucleotides in each of three possible positions in the codon (4 X 4 X 4 = 64).

The information contained in the DNA which is 'interpreted' by the cells to produce proteins. The chemicals ( nucleotides) which make up the DNA can be described by the letters A (Adenine), T (Thymine), C (Cytosine) and G (Guanine). Thus the genetic code can be written as a series of letters (for example AAA CGT TTC).

a term used to describe the arrangement of genes within the DNA of a living cells. In particular the order of the linear sequence of nucleotides (G, C, A and T) which make up genes.

The code in which the instructions of life are written. The genetic code refers to the sequence of bases in a DNA molecule. There are four possible bases, and their sequence spells out how to build proteins. In turn, the proteins are responsible for constructing and operating the features of the organism.

The correlation between the codons in genomic DNA or mRNA and the amino acid that each codon specifies. Codons are 3 nucleotides long, and since there are 4 bases (C, G, A, and T), there are 64 possible codons (4 x 4 x 4). There are 20 naturally occurring amino acids in proteins, some of which can be specified by more than one codon. 61 of the 64 possible codons specify amino acids, and the remaining 3 codons, called "stop codons", indicate the end of the protein sequence.

The rules that relate the four DNA or RNA bases to the 20 amino acids, There are 64 possible three-base (triplet) sequences, which are known as codons. A single triplet uniquely defines one amino acid, but an amino acid may be coded by as many as six codons, The code is thus said to be degenerate.

For example, the set AUG (adenine, uracil, guanine) calls for the amino acid methionine. The sequence of codons along a gene specifies the sequence of amino acids in a particular protein. Instructions appearing in the genes are converted ( transcription) in RNA, and then translated ( translation) in protein

The ‘languageâ€(tm) in which DNA's instructions are written. Every one of the 25,000 genes in each of our cells carries the information to make a single protein from amino acids. The sequence of bases along the gene specifies the sequence of amino acids in the protein. However, there are only four bases, and there are twenty types of amino acid. So the bases are ‘readâ€(tm) three at a time, to make enough combinations of three bases to specify every type of amino acid. For example, the three-base sequence ‘GAAâ€(tm) specifies the amino acid 'glutamate'. Remarkably, the genetic code is almost identical in every organism on the planet, e.g., the same ‘codonâ€(tm) (sequence of 3 bases) in a hamster specifies the same amino acid as it does in a human.

The instructions in a gene that tell the cell how to make a specific protein. A, T, G, and C are the "letters" of the DNA code; they stand for the chemicals adenine, thymine, guanine, and cytosine, respectively, that make up the nucleotide bases of DNA.

The base triplets (codons) in DNA that specify the amino acids that make up the polypeptide chains. The code is said to be degenerate, in that more than one codon specifies one amino acid. In other words, there are synonyms for the amino acids. The code is universal since codons are the same in all organisms.
