Mitochondrial DNA
Mitochondrial DNA was discovered in the 1960s by Margit M. K. Nass and Sylvan Nass by electron microscopy as DNase-sensitive threads inside mitochondria, and by Ellen Haslbrunner, Hans Tuppy and Gottfried Schatz by biochemical assays on highly purified mitochondrial fractions.

Sir Lawrence Bragg's original announcement of the discovery of the structure of DNA was made at a Solvay conference on proteins in Belgium on 8 April 1953 but went unreported by the UK press. He then gave a talk at Guy's Hospital Medical School in London on Thursday 14 May 1953, which resulted in an article by Ritchie Calder in the "News Chronicle" of London on Friday 15 May 1953, entitled "Why You Are You. Nearer Secret of Life".
