Codon (Anthromorphemics)

A sequence of three bases on the DNA molecule that codes a specific amino acid or other genetic function.


Codon (Anthropology)

A sequence of three bases on the DNA molecule that codes a specific amino acid or other genetic function.


Codon (Bioinformatics)

A sequence of three adjacent nucleotides that designates a specific amino acid or start/stop site for transcription.


Codon (Biotechnology)

A triplet of nucleotides in a DNA or RNA molecule that codes for one of the 20 amino acids in proteins, or for a signal to start or stop protein production. Each gene that codes for protein is a series of codons that gives the instructions for building that protein.


Codon (Evolution)

A triplet of bases (or nucleotides) in the DNA coding for one amino acid. The relation between codons and amino acids is given by the genetic code. The triplet of bases that is complementary to a condon is called an anticodon; conventionally, the triplet in the mRNA is called the codon and the triplet in the tRNA is called the anticodon.


Codon (Fossils)

A triplet of bases (or nucleotides) in the DNA coding for one amino acid. The relation between codons and amino acids is given by the genetic code. The triplet of bases that is complementary to a condon is called an anticodon; conventionally, the triplet in the mRNA is called the codon and the triplet in the tRNA is called the anticodon.

Codon (Genetics)

Three sequential nucleotides in DNA. One codon specifies (or codes for) a single amino acid – the building block of proteins. There are as many codons in a gene as there are amino acids in the protein made from that gene.

Codon (Genetics and Genealogy)

Three bases in a DNA or RNA sequence which specify a single amino acid. See Genetic Code.


Codon (Genome)

See: genetic code

Codon (HIV and AIDs)

A three-NUCLEOTIDE genetic subunit that determines which AMINO ACID is placed in sequence in a PROTEIN chain. Mutations at specific HIV codons are associated with changes in the amino acid sequence of HIV's proteins and ENZYMES. Such MUTATIONS help HIV evade the effects of ANTIVIRAL drugs or specific IMMUNE RESPONSES.


Codon (Huntingtons Disease)

A sequence of three DNA bases that codes for a specific amino acid; a “chemical blueprint” for building amino acids from DNA.


Codon (Microbiology)

A group of three consecutive nucleotides within messenger RNA (mRNA) that encodes a message to initiate translation, to incorporate a specific amino acid into the growing polypeptide chain, or to stop translation. The sequence of codons in the mRNA unambiguously defines the primary structure of the final protein. Of course, the codons in the mRNA were also present in the genomic DNA, but the sequence may be interrupted by introns. (See genetic code also).


Codon (Science)

A sequence of three bases in messenger RNA which represent a certain amino acid
