An understanding of the origin and dynamics of heritable genetic variation within classical animal breeding programs is needed to provide the context for understanding the contributions and concerns ...

Epigenetic aging clocks use DNA methylation patterns to measure biological age and predict health risks across human tissues.

Liquid biopsies are tests that detect signs of cancer through a simple blood draw. Unlike traditional biopsies, which require removing a piece of tissue, a liquid biopsy typically looks for mutations ...

Liquid biopsies have transformed cancer testing. These tests detect signs of cancer using a simple blood draw instead of removing tissue from the body. Traditional biopsies involve surgery, needles, ...

Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint for these cells is essentially the same. Where do those differences come ...

An important DNA modification is methylation, or the addition of a methyl group to the 5th carbon of cytosine. This forms 5-methylcytosine (5mC), typically associated with repression of gene ...

An ad hoc committee appointed by the National Academies to explore heritable genetic modifications of food animals. This committee will address methods for heritable genetic modifications and identify ...
