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.
Alan J. Cooper
Cooper is known as one of the pioneers of ancient DNA research, performing some of the first Polymerase chain reaction-based studies with Svante Paabo and Allan C. Wilson at UC Berkeley in 1989. In 2001, he used these methods to characterise the first complete genome sequences from an extinct species, mitochondrial genomes from two New Zealand moa.
