[Parallel changes in the puffing of polytene chromosomes and bioelectric properties of salivary gland cell nuclei in Drosophila melanogaster after heat shock]

Abstract

The dynamics of heat-shock puff activity and cell nuclei electrophoretic mobility in the larvae salivary glands of normal and temperature-sensitive mutant stocks of Drosophila melanogaster after heat shock (37 degrees C) were studied. The parallel changes of these characters and interlinear differences affected by ts mutation were found. Positive correlation between heat shock puff size and cell nuclei electrophoretic mobility was detected.
