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 reverse transcriptases, Drt3a and Drt3b, and a piece of noncoding RNA (ncRNA). Together, this trio makes long, double-stranded DNA consisting of alternating repeats (GT/AC).
