Who discovered DNA in what year?

Answer 1

The discovery of deoxyribonucleic acid, otherwise known as DNA, was made by Frederick Miescher, but the structure was discovered by James Watson and Francis Crick in 1953.

Rosalind Franklin produced vital images of DNA through x-ray crystallography with which Watson and Crick were able to deduce the structure of DNA. Watson and Crick acquired Franklin's data (without her permission) and used it to propose a structure for DNA, which is now known to be correct (B form DNA). Some other data, other than Franklin's, was also taken into account.

As a result, Watson and Crick are largely recognized as discovering the structure of DNA for the first time, but it was really Watson, Crick and Franklin (among other, less influential, work by other scientists).

Answer 2

Although something called DNA was known to exist much earlier, the precise structure of DNA was first discovered in 1953 by Dr. James Watson, Dr. Francis Krick, Dr. Rosalind Franklin and Dr. Maurice Wiklins
