Each cell in the body stores its genetic information in DNA in a stable and protected form that is readily accessible for the cell to carry on its activities. Nevertheless, mutations — changes in ...

These mutations may change the activity of a protein if they occur within a gene. This might result in a change in phenotype or it might appear hidden, and be unnoticed. Alternatively, they might ...

Two siblings who have the only known mutations in a key gene anywhere in the world have helped scientists gain new insights that could help progress the search for new treatments in type 1 diabetes.

Astronauts' blood can show signs of DNA mutations after spaceflight and therefore their cancer risk should be monitored, a new study reveals. Fourteen astronauts from NASA's space shuttle program who ...

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 ...

There are many different types of mutations which can arise in DNA. This diagram shows the normal order of the bases for one of the strands in a DNA molecule. Only one of the strands of DNA is ...

Mitochondria act as energy factories in cells and have their own, separate DNA. Mutations to mitochondrial DNA (mtDNA) have been observed in cancer, but it has been unclear how these changes might ...

A man sits outside and holds a slim menthol cigarette between his fingers. Close-up with focus on the cigarette. The study provided a comprehensive examination of how lifestyle and environmental ...

A newly developed AI can predict which diseases specific genetic mutations are likely to cause, not just whether they are harmful. The breakthrough could speed up diagnoses and open new paths for ...

Genetic mutations already in the population today may make the X-men movies seem less like science fiction than you think. It turns out that there are some genetic mutations that seemingly give some ...
