| Abstract: | Many of the biological activities of living organisms are light dependent and revolve around the solar clock. A variety of
behaviours and physiological processes are under the control of internal biological clocks. These internal clocks are remarkably
synchronized with the external solar clock (day-night cycle of 24 hour periodicity). The molecular mechanisms of biological
clocks have recently been uncovered. Although there are several molecules, which have a key role to play in the functioning
of biological clocks, cryptochromes have been implicated to be of special importance. A detailed study of cryptochromes may
provide some answers to problems related to the abnormal functioning of biological clocks in humans. |
