What is the name given to DNA by Friedrich Meischer?

Options

  1. ANuclein
  2. BDouble Helix
  3. CX-ray diffraction
  4. DComplementary

Correct answer

A. Nuclein

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
