Multistep modeling (MSM) of biomolecular structure application to the A-G mispair in the B-DNA environment.
A multistep modeling procedure has been evolved to study the structural changes introduced by lesions in DNA.  We report here the change in the structure of regular B-DNA geometry due to the incorporation of Ganti-Aanti mispair in place of a regular G-C pair, preserving the helix continuity.  The energetics of the structure so obtained is compared with the Ganti-Asyn configuration under similar constrained conditions.  We present the methodology adopted and discuss the results.
