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 ...

The Human Genome Project changed everything. A map of the entire human sequence of DNA was the starting point for an enormous number of discoveries, from disease genes to how humans evolved. But DNA ...

A new platform identifies which genes drive particle assembly to engineer cells that yield more potent delivery vehicles.

Genetic regulation of glucose homeostasis is central to the maintenance of human health and the prevention of metabolic disorders such as type 1 and type 2 diabetes. Recent advances in molecular ...

CRISPR functions as a programmable genetic memory system derived from bacterial immune defenses against viral infections. Guide RNA allows for rapid multiplexed targeting compared to older ...

Genetic engineering, also known as genetic modification, is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to ...

Researchers have determined whether a specific chemical modification of a protein that packages the genome called a histone affects gene activity and cell proliferation. Researchers have determined ...

The prime editor is a fusion protein consisting of a catalytically impaired Cas9 nickase (Cas9n) and an engineered reverse transcriptase (RT). The Cas9n is guided by a prime editing guide RNA (pegRNA) ...

Over the past century, worldwide consumption of food-animal products such as meat, milk, and eggs has steadily grown due to increases in global population and per capita income that fuel demand for ...
