Paaiškinimas anglų kalba

• (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 factor..."
• Specific sequences of nucleotides along a molecule of DNA (or, in the case of some viruses, RNA) which represent functional units of HEREDITY. Most eukaryotic genes contain a set of coding regions (EXONS) that are spliced together in the transcript, after removal of intervening sequence (INTRONS) and are therefore labeled split genes.
