title: Temporal control of urate oxidase activity in Drosophila: evidence of an autonomous timer in malpighian tubules.
abstract: The appearance of urate oxidase activity in the Malpighian tubules of Drosophlia melanogaster is synchronized with the time of emergence of the imago from the puparium. A developmental clock within the Malpighian tubules specifies the time of appearances of urate oxidase activity.
