Gene amplification in Rhynchosciara (1955-1987).
A review is made of the evidence indicating the existence of gene amplification in Rhynchosciara, from the early cytological work to the more recent studies using cloned sequences from the DNA puffs. Mention is made of work still in progress which indicates that the transcription unit of a DNA puff is surprisingly complex.
