In biomolecular systems there are some electron rich and electron deficient sites and thus helps in the prediction of possible hydrogen bond formation within the system and the strength of the bond formed. Figures 11 & 12 represent the atomistic binding site for each of the drug-DNA complex along with corresponding H-donor/acceptor clouded regions at those binding sites. These clouded regions represent the atoms or group of atoms which have the tendency to donate/accept electrons for hydrogen bonding so as to achieve stability during the docking calculations. Whereas table summarizes the DNA bases involved in the formation of hydrogen bond between the DNA and ligands along with the length of the hydrogen bond.
