Despite Mutated Gene, Mouse Circadian Clock Keeps on Ticking

摘要

If you opened up a clock and took out the most important-looking cog in its works, how well do you suppose the clock would work? A team of neurobiologists recently tried an analogous experiment with the biological clocks of mice, knocking out a gene thought to encode a crucial part of the molecular machinery that generates circadian rhythms. To their great surprise, the clock didn't stop.
