Researchers better understand biological clock

Researchers at Harvard University and the Howard Hughes Medical Institute (HHMI) have discovered that a simple circadian clock found in some bacteria operates by the rhythmic addition and subtraction of phosphate groups at two key locations on a single protein. This phosphate pattern is influenced by two other proteins, driving phosphorylation to oscillate according to a remarkably accurate 24-hour cycle.
