Crick proposed central dogma to show the flow of information from DNA to proteins. Watson along with Crick gave the acceptable model to understand the structure of DNA. Miescher discovered the acid rich substances in the nuclei of pus cells as Nucleins. Franklin used X-ray diffraction technique and established the periodicity of DNA as 0.34nm.
