With the landmark discovery of the double-helical structure of DNA came the appreciation that the molecule’s two entwined strands are complementary — each serving as a template for the other during ...

DNA replication is usually a very precise, templated process, but some enzymes are capable of "doodling," which might lead to a new future in medical research.

Scientists at Stanford University have discovered that DRT3, a unique defense system found in bacteria, creates DNA to protect against viral infections. DRT3 is made up of two different enzymes called ...
