| hyponym | : | operon, |
| definition | : | a segment of DNA containing adjacent genes including structural genes and an operator gene and a regulatory gene (noun.body) |
| hyponym | : | cdna, complementary dna, |
| definition | : | single-stranded DNA that is complementary to messenger RNA or DNA that has been synthesized from messenger RNA by reverse transcriptase (noun.substance) |
| hyponym | : | episome, |
| definition | : | DNA that is not incorporated into the genome but is replicated together with the genome (especially in bacterial cells) (noun.substance) |
| hyponym | : | coding dna, exon, |
| definition | : | sequence of a gene's DNA that transcribes into protein structures (noun.substance) |
| hyponym | : | intron, noncoding dna, |

| part holonym | : | cistron, factor, gene, |
| definition | : | (genetics) a segment of DNA that is involved in producing a polypeptide chain; it can include regions preceding and following the coding DNA as well as introns between the exons; it is considered a unit of heredity (noun.body) |
