Question

3-25. The function of DNA is to while the function of RNA is to A) store information about proteins: construct proteins based on the information in DNA B) build proteins break down proteins c) act as a blueprint for proteins act as a blueprint for other biomolecules D) act as a blueprint for the body: synthesize whatever biomolecules are required for the body to function E) construct and store proteins, transport proteins to needed locations in the body 326.

Answer 1

3-22. Physiological pH is 7 where N terminus stays protonated and c terminus deprotonated. b is correct.

3-23. COO- and NH3+can undergo hydrogen bonding interaction.A.

3-24. 3 nucleotide involved, t-RNA and code amino acids. E is option.

3-25. A. Information is stored in DNA and RNA construct protein using the information. DNA does not construct or store protein.RNA does not break or transport protein.

3-26. Circle is polar which is part B and C. E is answer.

3-27. Carbon II, III, IV and V are chiral as four different substituents are attached.A is answer.
