A codon table can be used to translate a genetic code into a sequence of amino acids. The standard genetic code is traditionally represented as an RNA...

In molecular biology, a stop codon (or termination codon) is a codon (nucleotide triplet within messenger RNA) that signals the termination of the translation...

The start codon is the first codon of a messenger RNA (mRNA) transcript translated by a ribosome. The start codon always codes for methionine in eukaryotes...

Codon usage bias refers to differences in the frequency of occurrence of synonymous codons in coding DNA. A codon is a series of three nucleotides (a...

Degeneracy or redundancy of codons is the redundancy of the genetic code, exhibited as the multiplicity of three-base pair codon combinations that specify...

The Codon Adaptation Index (CAI) is the most widespread technique for analyzing codon usage bias. As opposed to other measures of codon usage bias, such...

point mutation in a sequence of DNA that results in a nonsense codon, or a premature stop codon in the transcribed mRNA, and leads to a truncated, incomplete...

frames are defined as spans of DNA sequence between the start and stop codons. Usually, this is considered within a studied region of a prokaryotic DNA...

Codon may refer to any of the following: a three-base sequence of DNA that encodes a single amino acid in the genetic code Codon (plant), a genus of plants...

machinery of a cell called the ribosome. Complementation of a 3-nucleotide codon in a messenger RNA (mRNA) by a 3-nucleotide anticodon of the tRNA results...

corresponding to the mRNA codon, in the case of the start codon, this is the amino acid methionine. The next codon (adjacent to the start codon) is then bound by...

binding of complementary transfer RNA (tRNA) anticodon sequences to mRNA codons. The tRNAs carry specific amino acids that are chained together into a polypeptide...

is an artificially modified genetic code in which one or more specific codons have been re-allocated to encode an amino acid that is not among the 22...

Codon schenckii is a species of flowering plant in the genus Codon. It is native to Namibia and the Northern Cape Province of South Africa. It is also...

genetic code, there are 43 = 64 possible codons (3 nucleotide sequences). For translation, each of these codons requires a tRNA molecule with an anticodon...

PMID 5080161. Codons can also be expressed by: CTN, ATH, TTR; MTY, YTR, ATA; MTY, HTA, YTG Codons can also be expressed by: TWY, CAY, TGG Codons can also be...

Codon royenii is a species of flowering plant in the genus Codon. It is native to Namibia and the Northern Cape Province of South Africa. It is also known...

important intron structures and regulatory sequences are derived from stop codons. In this introns-first framework, the spliceosomal machinery and the nucleus...

sequences as codons, groups of three nucleotides. Each codon represents a single amino acid in a protein chain. However, there are more codons (64) than...

nature of gene expression by codons, the insertion or deletion can change the reading frame (the grouping of the codons), resulting in a completely different...

encoded by the stop codons—TGA and TAG respectively.) The mismatch between the number of codons and amino acids allows several codons to code for a single...

The Koudounia (Greek: κουδούνια), are bell-like percussion instruments. Most often, they are made from copper and upon playing (that is, hitting them with...

is the initiation codon encoding a methionine amino acid at the N-terminus of the protein. (Rarely, GUG is used as an initiation codon, but methionine is...

was first isolated in 1921 by John Howard Mueller. It is encoded by the codon AUG. It was named by Satoru Odake in 1925, as an abbreviation of its structural...

Codon reassignment is the biological process via which the genetic code of a cell is changed as a response to the environment. It may be caused by alternative...

nearby UGA codon as selenocysteine (UGA is normally a stop codon). In some methanogenic prokaryotes, the UAG codon (normally a stop codon) can also be...

both carry a mutation at codon 178 of the prion protein gene. FFI is also invariably linked to the presence of the methionine codon at position 129 of the...
