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.

The first complete mitochondrial genome (16,338 base pairs) DNA sequence analysis of "Bos primigenius" from an archaeologically verified and exceptionally well preserved aurochs bone sample was published in 2010, followed by the publication in 2015 of the complete genome sequence of "Bos primigenius" using DNA isolated from a 6,750-year-old British aurochs bone. Further studies using the "Bos primigenius" whole genome sequence have identified candidate microRNA-regulated domestication genes
