Abstract excerpt

Puffs in the polytene chromosome of Drosophila melanogaster are characteristic of sites of high-level active transcription which can be observed directly under the microscope. We studied the dependence of puff formation on chromatin modifications at a site where a GAL4-inducible transgene is located in the 61C7 cytological region. Immunostaining of salivary gland polytene chromosomes indicated no increase of...
