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.

Describe how conservation of mass (actual, not theoretical) could be checked in the experiment performed.arrow_forwardWhat impact would adding twice as much Na2CO3 than required for stoichiometric quantities have on the quantity of product produced? Initial results attachedarrow_forwardGiven that a theoretical yield for isolating Calcium Carbonate in this experiment would be 100%. From that information and based on the results you obtained in this experiment, describe your success in the recovery of calcium carbonate and suggest two possible sources of error that would have caused you to not obtain 100% yield.
