One of the mysteries of the English language finally explained.
A sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule.
- ‘Biochemistry may explain why most of the exceptions to the genetic code involve stop codons.’
- ‘Due to the redundant nature of codons, the genetic code shows a significant level of neutrality.’
- ‘We split the observable changes in the aligned codons in the two sequences into a number of disjoint groups.’
- ‘An organism is defined through the set of preferred codons shaping its genome.’
- ‘In effect, the DNA blueprint is a succession of code words, each consisting of a set of three nucleotides, known as codons, in the gene.’
1960s: from code + -on.
