  1. The table depict inter-molecular hydrogen bonding differences between the two complexes based on 5000 structural frames obtained from molecular dynamics (MD) simulation during the 0.00 ns to 100.00 ns. Dist. Å (angstrom) illustrates distance between the hydrogen bonded donor atom and acceptor atom or length of hydrogen bond. D (A, C, T, G) denotes Deoxyribonucleotides
