Rockefeller scientists first to reconstitute the DNA 'replication fork'

When a cell divides, it must first make a copy of its DNA, a fundamental step in the life cycle of cells that occurs billions of times a day in the human body. While scientists have had an idea of the molecular tools that cells use to replicate DNA—the enzymes that unzip the double-stranded DNA and create "daughter" copies—they did not have a clear picture of how the process works.
