Scientists have known for decades that genes can be transferred from one species to another, both in animals and plants. However, the mechanism of how such an unlikely event occurs remained unknown.

In a new study, North Carolina State University researchers characterize a range of molecular tools to rewrite – not just edit – large chunks of an organism’s DNA, based on CRISPR-Cas systems ...

Transposons, or "jumping genes" – DNA segments that can move from one part of the genome to another – are key to bacterial evolution and the development of antibiotic resistance. Cornell University ...
