cistron

noun

1. The unit of hereditary material (e.g. DNA) that encodes one protein.

   “Holonym: locus”

   “Near-synonym: gene (often synonymous)”

   “The butterfly mimicry cluster is a good example. As the cistrons leave one body and enter the next, as they board sperm or egg for the journey into the next generation, they are likely to find that the little vessel contains their close neighbours of the previous voyage, old shipmates with whom they sailed on the long odyssey from the bodies of distant ancestors.”
