This video was produced by the Royal Institution as part of their Ri Advent Calendar series on chromosomes, which is supported by BBSRC.

In this video, BBSRC-funded researcher Professor Russell Foster, head of the Nuffield Laboratory of Ophthalmology at the University of Oxford, explains why chromosome 10 is his favourite -- it's the one that encodes for special light receptors in the eye that govern the body's biological clock.

These receptors are different to the rods and cones that help us see, and his team discovered that they use a pigment called melanopsin to detect changes in daylength, which is the crucial mechanism by which our biological clocks are regulated. This, in turn, affects aspects of our daily lives from our moods to when we eat to how we sleep.
