Summary Introduction

To explain: Watson and Crick model accounts for the data discussed in the text.

Introduction: The deoxyribonucleic acid (DNA) is a hereditary material that is found in almost all living organisms. The DNA is a double-stranded helix that contains genetic information for the organism to grow, function, development, and reproduction.

Explanation of Solution

The X-ray crystallography of the DNA is found by Rosalind Franklin. The structural properties of the crystal DNA specimen are exposed in the X-ray crystallography is exposed by Rosalind Franklin working along with Francis Wilkins revealed the structure of DNA in an X pattern. The X pattern of the X-ray crystallography by the Rosalind Franklin and based on some information knowledge, Watson and Crick constructed the double helical structure of the DNA. Though, Watson and Crick did not even perform single experiments, they gave the key data that nucleotides are intertwines to form the double helix of the DNA.

The DNA is made up of nucleotides, each nucleotide has a nitrogen base, a phosphate group, and a sugar group. The purines and the pyrimidines are the two nitrogen bases that give four types of nucleotides, the purine has adenine and guanine, pyrimidines contain thymine and cytosine. The adenine bonds with thymine and guanine bonds with cytosine. The double helix strand of DNA as two linear strand that is complementary to one another that are made up of nucleotide. The DNA data is used still today, is based on the Watson-Crick double helical structure.
