Who among the following analysed DNA for the first time ? A)Arthur Cornberg B)Hargobind Khurana C)M. W. Nirenberg D)Watson and Krick
Option D) James D Watson and Fracis Crick, the two scientists who discovered the structure of DNA in 1953. Watson and Crick took a crucial conceptual step, suggesting the molecule was made of two chains of nucleotides, each in a helix as Franklin had found, but one going up and the other going down. Crick had just learned of Chargaff’s findings about base pairs in the summer of 1952.
