Typically, the information encoded in DNA allows organisms to develop, function, and pass traits across generations. Yet DNA ...

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 ...

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 ...

A new liquid biopsy developed by researchers at the University of Chicago is offering a powerful new window into cancer’s earliest stages by flagging subtle shifts in the gut microbiome. Unlike ...

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 ...

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

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 ...
