A lot of people believe that Watson and Crick discovered DNA, but it is not the case. Rather, it was first identified by Friedrich Miescher who coined the term nuclein for this unknown substance. Later, a series of researchers carried out further work which revealed the details of DNA. Franklin's Photo-51 is one of the major clues for Watson and Crick for discovering DNA double helix. Without the work done by earlier scientists, Watson and Crick could not get into the conclusion of 1953 that DNA exists as a three-dimensional double helix. This discovery was a turning point which had significant impact on science for years to come. In this review, we aim to discuss how gene discovery has moved from the early theories to gene and finally to DNA.
