The type of interaction hold by double helical strand together has to be found. Concept introduction: Hydrogen bond- Hydrogen bond is the non-covalent bond which consists of hydrogen atom. Hydrogen bond forms the reversible bond between different hydrophilic groups. When two sides chains are react they release water molecule. This is a weak bond. Stacking interaction: Stacking interaction is the non-covalent interaction. These interactions are electrostatic and hydrophobic in nature. Stacking interaction depends on their dipole moments and aromaticity of bases. Two types of interaction found in nucleic acid double strand: Inter-strand stacking interaction. a) Intra-strand stacking interaction. For identify the stabilizing effects of base stacking, base pairs are consider more important instead of individual bases .This is the non-covalent and weak interaction consists of hydrogen atom and one donor and acceptor atoms.
