Karst Hoogsteen

Karst Hoogsteen is famous in the biochemistry world for noting a new base pairing form in DNA, now called Hoogsteen base pairs.[1] These base pairing intercede in the Watson-Crick base pairing, forging a base pair 'triplex'. The Base Pairs use the N7 Nitrogen as the accepter rather than the N1 as observed in Watson-Crick base pairing. This leads to a twisted, non-linear arrangement.
