It adaptively organizes these body functions into near-24-hour oscillations termed circadian rhythms. Biorhythms are often called clocks, and genes involved in rhythms, usually circadian rhythms, are referred to as clock genes.

MUTUAL MUTANT : The biological clock - DiVA Portal

Power Up Your Day Human beings are a diurnal species. The biological clock resides in the suprachiasmatic nucleus (SCN), a master pacemaker that regulates circadian rhythms in brain and body (Challet, 2007). Photic information from the retina reaches the SCN via a direct projection, the retinohypothalamic tract, and via an indirect projection originating in the intergeniculate leaflet. The master clock of the biological rhythm, located in the suprachiasmatic nucleus of the anterior hypothalamus, synchronizes the molecular biological clock found in every cell of most peripheral tissues. The human circadian rhythm is largely based on the light-dark cycle. In night shift workers, alt … This master clock in our brains regulates the activity of biological clocks (specific protein molecules) present in nearly every organ and tissue of our bodies.
