Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

It’s tricky to make an exact copy of yourself. Or at least it is for cells undergoing mitosis, where cells replicate everything inside of them, including their neatly packaged DNA, then split in half.

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 ...

Some of your most important life partners are the mitochondria that power all your cells. You and these little cellular powerhouses are in a 1.5-billion-year-old evolutionary relationship-but ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...
