Cytogenetic analysis of the second chromosome heterochromatin of Drosophila melanogaster.
This paper reports the cytogenetic characterization of the second chromosome heterochromatin of Drosophila melanogaster. High resolution cytological analysis of a sample of translocations, inversions, deficiencies and free duplications involving the pericentric regions of the second chromosome was achieved by applying sequential Hoechst 33258 and N-chromosome banding techniques to larval neurob...
متن کاملCytogenetic analysis of the cSOD microregion in Drosophila melanogaster.
This report describes the genetic organization of a euchromatic region on the third chromosome of Drosophila melanogaster extending cytologically from 68A2 to C1, an interval comprising 10 or 11 polytene chromosome bands. The gene for cytoplasmic superoxide dismutase (cSOD) maps within this interval, as does low xanthine dehydrogenase (lxd).--Recessive lethal mutations were generated within the...
متن کاملCytogenetic analysis of the third chromosome heterochromatin of Drosophila melanogaster.
Previous cytological analysis of heterochromatic rearrangements has yielded significant insight into the location and genetic organization of genes mapping to the heterochromatin of chromosomes X, Y, and 2 of Drosophila melanogaster. These studies have greatly facilitated our understanding of the genetic organization of heterochromatic genes. In contrast, the 12 essential genes known to exist w...
متن کاملA cytogenetic analysis of cyclic nucleotide phosphodiesterase activities in Drosophila.
The genome of Drosophila melanogaster has been surveyed for chromosomal regions which exert a dosage effect on the activities of cAMP phosphodiesterase or cGMP phosphodiesterase. Two regions increase cAMP phosphodiesterase activity when present as duplications. A region of the X chromosome increases cAMP phosphodiesterase activity when duplicated and decreases that activity when deficient. This...
متن کاملMolecular and cytogenetic characterization of a metallothionein gene of Drosophila.
A chromosomal DNA segment containing the metallothionein gene was isolated from a genomic library of Drosophila melanogaster using a previously characterized cDNA of this species as a probe. A segment of 1543 base pair (bp) was sequenced and found to include the cDNA sequence interrupted by one small intron. Several lines of evidence indicate that there is a single copy of the metallothionein g...
