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.
Jodi Nunnari
Nunnari was born in Cleveland, Ohio, and studied chemistry at the College of Wooster before obtaining a Ph.D. in pharmacology from Vanderbilt University, working with Lee Limbird. As a postdoctoral fellow with Peter Walter at the University of California, San Francisco, Nunnari pioneered the use of green fluorescent protein to visualize mitochondria in budding yeast, helping to establish the field of mitochondrial dynamics. Since obtaining an independent position at the University of California, Davis, Nunnari and colleagues have investigated the molecular mechanisms underlying mitochondrial fission and fusion and explored the structure and function of membrane contact sites that link mitochondria with other organelles.
