Induction of Low-Molecular-Weight Heat-Shock Proteins in Drosophila and Human Embryonic Lineage Cells After Teratogen Exposure

Organisms most often carry out their developmental program and respond to a variety of environmental changes by modifying their set of transcriptionally active genes. Molecular biology advances, such as solution and solid support hybridization, reporter gene constructs, in situ

transcription, and PCR, have allowed developmental biologists to investigate the temporal and spatial regulation of such events.
