DNA sequences that can fold into shapes other than the classic double helix tend to have higher mutation rates than other regions in the human genome. New research shows that the elevated mutation ...

What Is the MTHFR Gene Mutation? The MTHFR gene mutation is a variation in the MTHFR gene. This gene normally tells your body how to make the MTHFR protein. You need this protein to process folate, ...

Experiments from the 1940s established a key tenet of genetics—mutagenesis occurs randomly across the genome. New research, however, suggests that mutations may be less random than originally thought.

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 ...

A new analysis of difficult-to-access genetic variation is the most comprehensive ever conducted in plants. It could guide the improvement of tomatoes and other crops. Human appetites have transformed ...

From chihuahuas to great Danes, dogs differ more in size than any other mammal species on the planet. A mutation behind such variation has been traced to an unexpected source: ancient wolves. The ...
