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.

Together with the geneticist A.V. Nedoluzhko, he conducted Russia's first complete sequencing of the DNA of ancient mitochondrial genome. This DNA sample was isolated from the mitochondria of skeletal remains from the burial ground Klady.
