BigField GEG Tech's insight:

The source of any life involves the duplication (or replication) of DNA, a mechanism that is essential to cell division. A team of biologists has recently performed the most exhaustive analysis to date of thousands of sites (called origins) where this replication of the genome is initiated in multicellular organisms.
