Researchers at the Francis Crick Institute and UCL have analyzed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through ...

The DNA mutations that drive evolution are generally thought to be fairly random, but a new study suggests there’s some order to the chaos. Comparing the genomes of hundreds of plants grown in a lab, ...

The human genome is made up of 23 pairs of chromosomes, the biological blueprints that make humans … well, human. But it turns out that some of our DNA — about 8% — are the remnants of ancient viruses ...

A mystery that started with the discovery of a pinkie finger bone in Denisova Cave in the Altai Mountains of southern Siberia may finally have been cracked.

Bar-Ilan University study shows that even jellyfish and sea anemones repair DNA during repose, underscoring the fact that a ...

SAN FRANCISCO, CA—January 13, 2023—Humans and chimpanzees differ in only one percent of their DNA. Human accelerated regions (HARs) are parts of the genome with an unexpected amount of these ...

Scientists have shown that in one in every 4,000 births, some of the genetic code from our mitochondria – the ‘batteries’ that power our cells – inserts itself into our DNA, revealing a surprising new ...

DNA codes offer new evidence of evolution. DNA, the genetic blueprint for living things, is like a text made up of chemical letters. For many decades, reading the sequence of letters in DNA was a ...

Researchers have identified evolutionary hotspots in DNA where mutations are more likely. The study authors say these findings will help us in the future to predict the evolution of bacteria and ...

DNA repair pathways exist to correct molecular damage caused by internal and external factors. However, any damage to these pathways can result in the creation of tumors and specific types of cancers.
