Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a ...

Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

DNA replication is a complex process with many moving parts. In baker's yeast, the molecular complex Ctf18-RFC keeps parts of the replication machinery from falling off the DNA strand. Human cells use ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a cell divides – which they ...

Franklin W. Stahl, an American molecular biologist whose landmark 1957-58 experiment with colleague Matthew Meselson revealed how DNA replicates, helping pave the way for a revolution in genetics ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...
