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 ...

Every cell type in the human body carries the same approximately 3.2 billion base pairs of DNA, yet a liver cell behaves nothing like a neuron. The epigenome explains this difference: in each cell, ...

Scientists at a NY university say they can bring back the near extinct American chestnut tree, wiped out a century ago, ...

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 ...

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 ...

This Brush Up is sponsored by Cayman Chemical. Learn more about chemical inhibitors of histone modification. Histone modification affects how tightly DNA wraps around histone proteins, yielding ...

Collaborating researchers have made a breakthrough discovery regarding the intricate defense systems of bacteriophages (phages)—viruses that can specifically target harmful bacteria without harming ...

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 ...
