a)
Interpretation:
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
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.
b)
Interpretation:
The covalent bond interaction hold by double helical strand together is not good; the reason has to be found.
