Interpretation: The reason corresponding to the fact that the two purine bases (
Concept introduction: The building block of DNA and RNA is
(b)
Interpretation: The reason corresponding to the fact that the hydrogen bonding between guanine and cytosine is more favorable than hydrogen bonding between guanine and thymine is to be stated.
Concept introduction: The building block of DNA and RNA is nucleotide. It is an organic molecule. There is a specific structure for each and every nucleotide which enables the formation of DNA and RNA. DNA is composed by the four nitrogenous bases. These are connected by the chemical bond.

- 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_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_forwardThe base composition for one of the strands of a DNA double helix is 19% A, 34% C, 28% G, and 19% T. What is the percent base composition for the other strand of the DNA double helix?arrow_forward
- 22-85 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_forwardThe sequence of a short DNA segment is ATGGCAATAC. (a) What name do we give to the two ends (terminals) of a DNA molecule? (b) In this segment, which end is which? (c) What would be the sequence of the complementary strand?arrow_forwardFrom examination of the molecular models i–v, choose thesubstance that (a) can be hydrolyzed to form a solutioncontaining glucose, (b) is capable of forming a zwitterion,(c) is one of the four bases present in DNA, (d) reacts withan acid to form an ester, (e) is a lipid.arrow_forward
- In which solvents or solutions will a lipid be soluble: (a) CH 2Cl 2; (b) 5% aqueous NaCl solution; (c) CH 3CH 2CH 2CH 2CH 3?arrow_forwardWhich statement best explains the chemical differencesbetween DNA and RNA? (a) DNA has two different sugarsin its sugar–phosphate backbone, but RNA only has one.(b) Thymine is one of the DNA bases, whereas RNA’s correspondingbase is thymine minus a methyl group. (c) TheRNA sugar–phosphate backbone contains fewer oxygenatoms than DNA’s backbone. (d) DNA forms double helicesbut RNA cannot.arrow_forward"There are ten HIV protease inhibitors approved by the FDA; those inhibitors include: saquinavir, indinavir, ritonavir, nelfinavir, amprenavir, fosamprenavir, lopinavir, atazanavir, tipranavir, and darunavir. Shown below is the structure of one of those compounds: H (a) Determine its molecular formula. (b) Identify whether the molecule contains any of the following functional groups. If it does, draw an arrow to the group and label it: ester, primary amide, secondary amide, tertiary amide, primary alcohol, secondary alcohol, tertiary alcohol, primary amine, secondary amine, tertiary amine, ketone, aldehydearrow_forward
- (b) Which of the following common amino acids has more than one amino group?arrow_forwardMethanogens are prokaryotes that produce methane according to the net equation H2 + CO2→CH4 + 2H2O. Some bacteria consume methane according to the net equation CH4 + SO42- →HCO3- + HS− + H2O. (a) Classify these two types of bacteria as autotrophic or heterotrophic. (b) Explain why the two types of bacteria are often found associated with each other.arrow_forwardThe structural formula for the open-chain form of galactose is CH Н—ҫ—ОН Но—С—н НО—С—Н Н—ҫ—ОН CH-ОН (a) Is this molecule a sugar? (b) How many chiral carbons are present in the molecule? (C) Draw the structure of the six-member-ring form of this molecule.arrow_forward
