Abstract
A genomic clone containing Drosophila sn-glycerol-3-phosphate dehydrogenase sequences has been isolated using a mixture of synthetic tridecanucleotides as a hybridization probe. The clone as well as the synthetic probe mixture was found to hybridize to an abundant poly(A)+ RNA of 1700 bases. A partial DNA sequence obtained for a 40-amino acid region containing the oligonucleotide hybridization site was found to agree with the known Drosophila protein sequence data for this region of the protein. In situ hybridization of this clone to the polytene chromosomes of wild type flies and flies bearing chromosomal aberrations that delimit the Gpdh+ locus have allowed us to decisively place the gene in the distal region of 26A on the left arm of the second chromosome.
