Chapter 12, Problem 42A

Summary Introduction

To draw:

The DNA structure from the given information.

Introduction:

DNA is deoxyribonucleic acid. It acts as genetic material in almost all living beings. It can be circular in nature and linear in nature. DNA is double stranded in nature and carries genetic information from one generation to another.

Explanation of Solution

According to the given information, DNA is a double stranded structure, where nucleotide base of one strand forms hydrogen bond with nucleotide base on the other strand. These nucleotides should be complementary to each other. This means, Adenine will form hydrogen bond with thymine only, and guanine will form hydrogen bond with cytosine only. Moreover, DNA is a double helical in structure.
