Explanation
It is a misconception that Dr. James Watson, Dr. Francis Crick, M.H.F. Wilkins, and Rosalind Franklin discovered DNA. In fact, on the basis of Wilkins’ X-ray analysis, Watson and Crick presented the double-helix structure of DNA in 1953. Actually, DNA was first identified in 1869 by the Swiss chemist Friedrich Miescher. Friedrich called it “nuclein.”
