Summary Introduction

Introduction:

There are four types of specific nitrogenous bases that can be easily found in a DNA molecule. Two of these nitrogenous bases, adenine, and guanine have a double-ring structure which is characteristic of a chemical called purine. The other two bases, cytosine, and thymine have a single-ring structure and are the characteristic of a chemical called pyrimidine.
