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 ...

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 ...

An animal geneticist at the University of California-Davis told Kansas cattle producers recently that a gene editing technique more common in plant genetics is also a safe option for shortening the ...

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) ...

These approaches, collectively known as T-DNA-free genome editing, allow scientists to modify crop traits while avoiding the persistent transgenic sequences often associated with conventional CRISPR ...

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 ...

Could we genetically optimize human beings? This scenario, which sounds like something out of science fiction, has never been so close. It raises ethical questions, which Bertolt Meyer, who was born ...

A committee-supported project or activity that has been completed and for which output dissemination has begun. Its committee has been disbanded and closeout procedures are underway. An ad hoc ...
