Detailed explanation-1: -Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule. Watson and Crick realized that DNA was made up of two chains of nucleotide pairs that encode the genetic information for all living things.
Detailed explanation-2: -Advanced at the beginning of the 20th century by Dutch botanist and geneticist Hugo de Vries in his Die Mutationstheorie (1901–03; The Mutation Theory), mutation theory joined two seemingly opposed traditions of evolutionary thought.
Detailed explanation-3: -What did the duo actually discover? Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.
