title: Two protein-binding sites in chromatin implicated in the activation of heat-shock genes.
abstract: The resistance to exonuclease digestion of two regions of chromatin at the 5' end of heat-shock genes in Drosophila implies they have protein bound to them. The pattern of resistance before and after induction of gene expression suggests that heat-shock genes are activated by the sequential binding of at least two protein factors.
