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.
Masayori Inouye
Masayori Inouye is a Japanese biochemist who, along with his team, discovered natural antisense RNA.
Inouye was also a key scientist involved in the discovery and characterization of retrons, which are retroviral-like elements found in various bacterial genomes. Retrons produce small satellite DNA known as multi-copy single stranded DNA (msDNA) and have recently been demonstrated to be important virulence determinants for gastrointestinal disease (Elfenbein et al., 2013)
