A phenol oxidase enzyme (PHOX) has been identified on electrophoretic gels following simple activation by 50% propan-2-ol in phosphate buffer. Three electrophoretically detectable allozymes were found in natural populations and a structural locus (Phox) for this enzyme was mapped to position 80.6 on

โฆ Synopsis
Dipeptidase A (Dip-A), a new peptidase locus in Drosophila melanogaster, is located on the second chromosome at map position 55.2 and in the 41A-B; 42A2-3 interval in the salivary gland chromosomes. Three alleles are reported. In the Carpenter, North Carolina population the allele frequencies are: Dip-A 6

We have continued the transcriptional analysis of the region of cytological locus 67B that contains the four small heat shock genes and other genes. Transcription from one of the heat shock genes in the region, hsp 26, takes place during high temperature treatment and at certain developmental stages
A natural population of D. melanogaster from Korea (Chungju) has been examined with respect to inversion polymorphism. Thirteen different inversions were found distributed approximately equally on chromosome pairs II and III. Some of them proved to be frequent and cosmopolitan, others rare and endem
