The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

A research group led by the University of Osaka has discovered that the DNA repair enzyme Polβ plays a crucial role in protecting the developing brain from harmful mutations. The study found that a ...

Researchers at the University of Toronto have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and ...

A new study adds to an emerging, radically new picture of how bacterial cells continually repair faulty sections of their DNA. A new study adds to an emerging, radically new picture of how bacterial ...

The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break-when both sides of the DNA helix are cut at once. Healthy cells can normally fix ...

Inside every human cell, tiny mitochondria quietly convert nutrients into usable energy, keeping organs running and immune defenses primed. Now researchers have identified a previously unknown form of ...

The tiny little powerhouses of our cells, the mitochondria, are unique among organelles because they carry their own tiny ...

An analysis of genetic data from over 900,000 people shows that certain stretches of DNA, made up of short sequences repeated ...
