Abstract
A comparison between chromosomal puffs induced by temperature shocks and dinitrophenol in regions 87 A and 87 B of salivary gland chromosome 3 R of Drosophila melanogaster is presented. The size of both puffs can be regulated by either the temperature of a heat-shock or by the concentration of dinitrophenol. The two agents are additive with respect to their effects upon puff size, supporting the idea that both result in a change in ATP synthesis within the cell. A possible relationship between these agents and puff formation and RNA metabolism is discussed.
