Genes are short sections of DNA that determine an animal’s traits—everything from coat color and claw strength to body shape ...

KRAS is the most frequently mutated oncogene across all human cancers. Although different KRAS mutations have long been thought to exert the same cancer-driving effects, a new study led by UT ...

Genetic disorders — like cystic fibrosis and Huntington’s disease — are considered incurable, with gene mutations occurring in essentially every cell of the body. Gene mutations occur when one ...

Although previously thought to be neutral, research in yeast suggests that synonymous point mutations may have strongly nonneutral effects. A group of researchers from the University of Michigan (MI, ...

A study demonstrates that the 'previous state' of blood stem cells plays a decisive role in the subtype of leukemia that develops. The new technique, called STRACK, allows monitoring of the evolution ...

Researchers have documented that corals can pass mutations acquired during their lifetimes to their offspring, providing increased genetic diversity for potential evolutionary adaptation. In a ...

Since the Chernobyl nuclear disaster in 1986, something has concerned scientists: can exposure to radiation leave marks in someone’s DNA that are passed on to ...
