Chapter 13.2, Problem 13.2YT

(a)

Interpretation Introduction

Interpretation: The chemical formulas for the ribose and Deoxyribose sugars have to be given.

Concept Introduction:

Concept of Nucleic acids:

• • Nucleic acids are biopolymers that are essential to all forms of life.
• • The nucleic acid is composed of nucleotides.
• • The nucleotides are composed of monomers.
• • The monomers are made of three components such as 5-carbon sugar, a phosphate group and a nitrogenous base.
• • The 5-carbon sugar can be ribose or deoxyribose sugar.
• • If the 5-carbon sugar is a ribose unit, then the overall nucleic acid is known as ribose nucleic acid which is abbreviated as RNA.
• • If the 5-carbon sugar is a deoxyribose unit, then the overall nucleic acid is known as deoxyribose nucleic acid which is abbreviated as DNA.

(b)

Interpretation Introduction

Interpretation:

The structural formulas of the ribose and deoxyribose sugars have to be differentiated.

Carbohydrates are the sugars that are found in the basic food and provide energy to the human bond to perform various works.

(d)

Interpretation Introduction

Interpretation: In the ribose and deoxyribose sugar units, the atoms that would form hydrogen bonds with water or other nucleic acids are to be shown.

Concept Introduction:

Hydrogen bonding:

• • Hydrogen bonding is a special type of dipole-dipole interaction in a polar bond which has hydrogen atom and a highly electronegative atom such as Nitrogen, Oxygen and Fluorine.
• • Hydrogen bonding can also be defined as coulombic attraction between the hydrogen atom and an electronegative atom.
