“A system of biological clocks controls the daily, or circadian, rhythms of the body. These roughly 24-hour cycles of physical, mental and behavioral changes are found in most organisms, from humans to fruit flies, plants and even tiny microbes.”

The Mammalian Molecular Clock Model

“These oscillations are the molecular ‘gears’ of the biological clock regulating our 24-hour rhythms. A key feature of these molecular oscillations is the negative feedback loop formed when the protein product of a gene actually turns off production of more protein.”

The Suprachiasmatic Nucleus, Circadian Clocks, and the Liver

“The circadian clock system adapts phasic physiological activities, such as sleeping and eating, to environmental cycles. The “master clock” is in the suprachiasmatic nucleus (SCN) and the principal cue (Zeitgeber) is the light–dark cycle, around which most mammalian (and those of all living organisms) functions have evolved.”
