(B) DNA is an acidic substance present in the nucleus was first identified by Friedrich Meischer in 1869. (C) The X-ray diffraction data was used for discovery of the DNA (D) Two strands are anti-parallel to each other.

Tardigrade Admin · Accepted Answer

In 1953, 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. They have not used this data for the discovery of DNA. DNA as an acidic substance present in the nucleus was first identified by Friedrich Meischer in 1869.
