Structurally, a basic unit of hereditary material; an ordered
sequence of
nucleotide bases that encodes one polypeptide chain (via
mRNA). The gene includes, however, regions preceding and following the coding region (leader
and trailer) as well as (in eukaryotes) intervening sequences (
introns) between individual coding segments (
exons). Functionally, the gene is defined by the
cis-trans test that determines whether independent
mutations of the same
phenotype occur within a single gene or in several genes involved in the same function.
