Successful DNA replication in cyanobacteria depends on the circadian clock

A new study from the University of Chicago has found that the photosynthetic bacterium Synechococcus elongatus uses a circadian clock to precisely time DNA replication, and that interrupting this circadian rhythm prevents replication from completing and leaves chromosomes unfinished overnight. The results, published online on May 10 in Circadian rhythms are the internal 24-hour clock possessed by most organisms on...
