Many people are familiar with histamine, a biological molecule that serves as a key driver of allergic reactions and other ...

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, ...

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.

Despite progress in defining functional elements of noncoding DNA, it is still not fully understood. Researchers, using an experiment that elucidated the function of tens of thousands of noncoding ...

The risk of older fathers passing on disease-causing mutations to their children is higher than we thought. Genome sequencing has revealed that among men in their early thirties, around 1 in 50 sperm ...
