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.

- 22-62 Distinguish between intermolecular and intramolecular hydrogen bonding between backbone groups. Where in protein structures do you find one, and where do you find the other?arrow_forward22-85 Denaturation is usually associated with transitions from helical structures to random coils. If an imaginary process were to transform the keratin in your hair from an (-helix to a (-pleated sheet structure, would you call the process denaturation? Explain.arrow_forward21-90 To what extent do lipids and carbohydrates play structural roles in living organisms? Do these roles differ in plants and in animals?arrow_forward
- Although RNA is single-stranded, the strand sometimes folds back on itself to give a complementary portion. What would be the complementary portion of the RNA fragment having the bases uracil-cytosine-guanine? A virus is a particle that contains DNA or RNA that is surrounded by a coat of protein that can replicate only in a host cell. The influencza virus shown in this electron microscope image is an RNA virus.arrow_forwardDescribe the structural differences between DNA and RNA. The monomers in nucleic acids are called nucleotides. What are the three parts of a nucleotide? The compounds adenine, guanine, cytosine, and thymine are called the nucleic acid bases. What structural features in these compounds make them bases? DNA exhibits a double-helical structure. Explain. Describe how the complementary base pairing between the two individual strands of DNA forms the overall double-helical structure. How is complementary base pairing involved in the replication of the DNA molecule during cell division? Describe how protein synthesis occurs. What is a codon, and what is a gene? The deletion of a single base from a DNA molecule can constitute a fatal mutation, whereas substitution of one base for another is often not as serious a mutation. Explain.arrow_forwarda. Use bond energies (see Table 3-3) to estimate H for the reaction of two molecules of glycine to form a peptide linkage. b. Would you predict S to favor the formation of peptide linkages between two molecules of glycine? c. Would you predict the formation of proteins to be a spontaneous process?arrow_forward
