While most known types of DNA damage are fixed by our cells’ in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

This goes against one of the key assumptions of the theory of evolution. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Genetic changes that ...

Mutations are changes in the molecular "letters" that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

Researchers have refined a powerful DNA sequencing tool that can uncover hidden mutations that occur naturally in our bodies as we age. In the largest study to date, they have used the tool to provide ...

Proteins are like Spider-Man in the multiverse. The underlying story is the same: each building block of a protein is based on a three-letter DNA code. However, change one letter, and the same protein ...

Scientists have created a new technique that can assess how mutations in the genome influence the packaging of DNA in cells. The genome is massive, and has to be carefully wrapped around proteins so ...

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, ...

Studying the genome of thale cress, a small flowering weed, led to a new understanding about DNA mutations. (Pádraic Flood) A simple roadside weed may hold the key to understanding and predicting DNA ...

Whether they're damaged by injury or disease, or simply conducting the daily maintenance required for life, organisms have to make new cells. That generally requires replicating the organism's genome ...

The study was published in the journal Nature on January 12th, 2022. Researchers from the University of California, Davis, and the Max Planck Institute for Developmental Biology in Germany sequenced ...
