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.
Baldomero Olivera
Baldomero Olivera (born 1941) is a Filipino chemist known for discovery of many cone snail toxins important for neuroscience. These molecules, called conotoxins, led to a breakthrough in the study of ion channels and neuromuscular synapses.
He discovered and first characterized E. coli DNA ligase, a key enzyme of genetic engineering and recombinant DNA technology.
