DNA is sophisticated. That means that there’s more opportunity for something to go wrong! If your DNA was all knotted up, then you’d be in trouble, but a little enzyme known as Topoisomerase II steps in. How does it work, and what are the implications? Dr. Joe Deweese earned his P.h.D. in Biochemistry from Vanderbilt University and in 2009, began teaching biochemistry and pharmacology at the Lipscomb University College of Pharmacy. His specialty is in DNA Topoisomerases – a fascinating field of research that will leave you in awe of God’s design.
