In this exercise we will be doing the following:. DNA Structure. The discovery of the structure. Francis Crick and James Watson. The deoxyribonucleic acid (DNA) molecule is the genetic blueprint for each cell and ultimately the blueprint that determines every characteristic of a living organism. The DNA molecule was discovered in 1951 by Francis Crick, James Watson, and Maurice Wilkins using X-ray diffraction. . Stryer. Short course. Chapter 33. Nucleic Acid Structure. Nucleobase.
