Gene
Of genetics, deoxyribonucleic acid, chromosome, sequence and molecular biology. May also be referred to as cistron and factor.
(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; "genes were formerly called factors".
