Every time a nucleated cell commits to becoming two cells, every &#8220;letter&#8221; of its genome must be replicated once and only once. In humans, the task boggles the imagination. If unwound, the double helix crammed into each of our cells would measure 6 feet in length. In our bone marrow alone, half a billion new cells are born every minute. These cells alone contain enough DNA to wrap around the earth&#8217;s equator 25 times. Within daunting tolerances, each new cell must have a genome identical to that of the cell that gave birth to it. Cancer and other diseases can result when the process goes awry.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Life would be impossible if the DNA in dividing cells were replicated with anything less than near-perfect precision.
