noun
- a segment of DNA that codes for a single polypeptide chain or functional RNA molecule
Usage: genetics; molecular biology
Examples
- Each cistron contains the genetic information needed to produce one protein.
- The researcher identified three cistrons within the DNA sequence.
- A mutation in this cistron could affect protein synthesis.
- The cistron was mapped to a specific location on the chromosome.
- Scientists studied how the cistron regulates gene expression.
- The cistron’s boundaries were determined through genetic analysis.
