Chapter 12, Problem 9E

Interpretation Introduction

Interpretation:

Guanine and Cytosine bases should be arranged to give the maximum number of Hydrogen bonds.

Concept introduction:

DNA consist of four types of bases. Adenine (abbreviated A), Cytosine (C), Guanine (G), and Thymine (T).Adenine and Guanines are called purines. These compounds are heterocyclic fused, five and six membered compounds. Cytosine and Thymine caller pyrimidine and those are typically single rings with six membered compounds.Based on the structure of the bases, cytosine can form three hydrogen bonds with Guanine and adenine can form two hydrogen bonds with thymine.
