Older DNA strands are preferentially sorted into stem cells when they self-renew (A). This segregates the DNA most recently replicated, and therefore most error-prone, into cells destined for ...

It’s generous to say that it took until just after the eight-minute mark in the second quarter of Oregon’s visit to New Jersey to prove what... Frank Stahl, a professor emeritus of molecular biology, ...

“This molecule is really unlike any other molecule that biologists have ever studied, before or since,” says Matthew S. Meselson, Thomas Dudley Cabot Professor of the Natural Sciences. The biologist’s ...

Consider, too, the research of two young postdocs — Matthew Meselson and Frank Stahl — in the years 1957–58, as they worked to find evidence for the semi-conservative form of DNA replication. Was this ...

We know DNA unzips to replicate itself, each new double helix containing half the parent. But how do we know that? An incredible experiment, conducted in the 1950s, proved how DNA replicated itself ...

Which books convey the excitement of the early years of molecular biology? Horace Freeland Judson's The Eighth Day of Creation published over twenty years ago succeeds as a vivid narrative, surveying ...
