The segment of DNA involved in producing a polypeptide chain. It includes regions preceding and following the coding region as well as intervening sequences (introns) between individual coding segments (exons). (Genes V, p.1242)
A temperature-sensitive mutant of the zyg gene. zyg-1(oj7), zyg-1(b1), zyg-1(it4), zyg-1(it37) are alleles of zyg-1 gene, each one resulting in temperature sensitive mutations. C. elegans II, p.1046
