A remarkably small bacterium containing fewer than 500 genes serves as the basis for one of the most detailed digital life ...

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 ...

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 ...

Six feet of DNA crammed into a cell nucleus narrower than a human hair: Life may pack no tighter puzzle than this. And yet, biology pulls it off every second, compressing genetic material with a ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study. In a new paper published in Nature Communications, an ...

Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell division - a discovery that could lead to new cancer therapies, according ...

Discovering How DNA Reaches Its Most Compact Form For many years, researchers did not know how this extra level of chromatin compaction occurred. In 2019, HHMI Investigator Michael Rosen and his team ...

Mitochondrial DNA has long been treated as a workhorse record of cellular history, but new research suggests it also hides a subtle and previously overlooked form of damage. By uncovering this cryptic ...
