Summary Introduction

To review:

The data that was available to Watson and Crick, other than Chargaff’s data, which suggested that adenine–guanine and cytosine–thymine pairs do not form normally.

Introduction:

Watson and Crick proposed the DNA (deoxyribonucleic acid) model, according to which a DNA molecule consists of two chains of polynucleotides wound around each other in the form of a double helix. Each monomer in the chain consists of deoxyribose, a phosphate group, and a nitrogen base. There are four nitrogenous bases in DNA, of which two are purines and two are pyrimidines.
