Options

  1. AFriedrich Miescher
  2. BJames Watson and Francis Crick
  3. CThomas hunt morgan
  4. DMaurice Wilkins

Correct answer

B. James Watson and Francis Crick

Step-by-step solution

DNA as an acidic substance present in nucleus was first identified by Friedrich Meischer in 1869. He named it ‘Nuclein’. However, due to technical limitations in isolating such a long polymer intact, the elucidation of structure of DNA remained elusive for a very long period of time. It was only in 1953 that James Watson and Francis Crick, based on the X-ray diffraction data produced by Maurice Wilkins and Rosalind Franklin, proposed a very simple but famous Double Helix model for the structure of DNA. One of the h
