This article attempts to summarize, and review the basic history of DNA while providing some fascinating information about it.

A Brief Historic Review Throughout the early 19th and 20th century, many scientists have studied deoxyribonucleic acids in order to attain higher understanding over the matter. Johann G. Mendel had figured out and understood the laws of heredity. Friedrich Miescher discovered DNA

The pictures were shown to James Watson and Francis Crick by Maurice Wilkins. They were then able to confirm their theory about the 3D structure of DNA. In 1962, they were awarded the Nobel Prize in Physiology or Medicine for solving the structure of DNA. The Nobel committee could not award it to Franklin because the Nobel prize could only be shared by three people and also because she was already dead (DNA from the Beginning, 2011)
Origin of the Four Bases’ Names The four names of the nitrogenous bases of the DNA are adenine, thymine, guanine, and cytosine.

If a person typed 60 words per minute, eight hours a day, it would take approximately 50 years for them to type the human
