Definition of cistron in English:

cistron

noun ˈsɪstrɒnˈsisträn

Biochemistry

A section of a DNA or RNA molecule that codes for a specific polypeptide in protein synthesis.
〔生化〕顺反子
Example sentencesExamples
- Almost all eukaryotes have multiple copies of their nuclear ribosomal RNA cistrons, arranged in a long tandem array.
- We find that full function of the endogenous rDNA locus depends not merely on the presence of the rDNA cistrons but also on chromosomal context.
- Benzer called this unit the ‘cistron’; molecular biologists came to view the cistron as the nucleotide sequence encoding a single polypeptide.
- The estimate was defined at the scale of cistrons so as to exclude the possibility of recombination.
- Molecular evolution of the rDNA cistron in these plants typically follows the same trajectory.

Origin

1950s: from cis- (sense 3) + trans- (because of the possibility of two genes being on the same or different chromosomes) + -on.
