Several clocks may simplify the circadian system of Gonyaulax. 1996

The circadian system of Gonyaulax involves at least two pacemaking oscillators. These oscillators have been shown to be distinct at the physiological level by an examination of their rhythmic periods under different conditions, their phase response to pulses of light and darkness and their ability to compensate the rhythms for changes in temperature. It is also known that Gonyaulax can restrict synthesis of different proteins to at least three different times of day. We suggest that the two known oscillators may each control synthesis of a differently timed class of proteins.

D004141	Dinoflagellida	Flagellate EUKARYOTES, found mainly in the oceans. They are characterized by the presence of transverse and longitudinal flagella which propel the organisms in a rotating manner through the water. Dinoflagellida were formerly members of the class Phytomastigophorea under the old five kingdom paradigm.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
