New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins ...

DNA is well known as the blueprint of life, necessary for an organism to facilitate living processes. DNA can be damaged by various factors such as radical metabolites, radiation, and some toxic ...

Mitochondria are often described as the cell’s power plants, but a wave of new research suggests their genetic material may ...

Researchers have uncovered answers that provide the detail to explain two specific DNA repair processes that have long been in question. Researchers from the University of Birmingham have uncovered ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

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 ...

Homologous recombination is a DNA repair mechanism that counteracts double-stranded breaks in DNA. Researchers at Kindai University have recently revealed how the Sae2 protein coordinates with the ...

Cancer research, drug safety testing and aging biology may all gain a major boost from a new fluorescent sensor developed at Utrecht University. This new tool allows scientists to watch DNA damage and ...
