DNA was first discovered in 1869 by Swiss Friedrich Mieschler.

#ScienceFact

Although it was first labelled ‘nuclein’ - now known as deoxyribonucleic acid - Mieschler was the first to discover it, but Gregor Mendel had a theory on it in 1865. Wilhelm Johannsen then coined the term ‘gene’ to describe hereditary units in 1909. Forty-four years later; Francis Crick and James Watson made DNA far more well-known as they described the double-helix structure and made suggestions and the obvious, boring information.
