Abstract
The factors affecting the period are examined in a model for circadian oscillations of the period protein (PER) in Drosophila. The model for the circadian clock is based on multiple phosphorylation of PER and o n the negative feedback exerted by PER on the transcription of the per iod (per) gene. The results are used to address the possible bases of the relative invariance of the period of oscillations with respect to temperature. Such a phenomenon, referred to as temperature compensatio n, represents one of the most conspicuous properties of circadian rhyt hms.
