Abstract
There have been massive technological advances in molecular biology and genetics over the past five decades. I have personally experienced these advances and here I reflect on those origins, from my perspective, studying yeast mitochondrial genetics leading up to deciphering the functions of the mitochondrial genome. The yeast contributions commenced in the middle of the last century with pure genetics, correlating mutants with phenotypes, in order to discover genes, just like the early explorations to discover new lands. The quest was to explore the mitochondrial genome and find its genes and their products. It was most fortunate that DNA sequencing technologies became available in the late 1970s, and laboratories were restructured enormously to keep pace with the emerging technologies. There were considerable costs in equipping laboratories, purchasing ultracentrifuges and restriction endonucleases, and undertaking DNA sequencing; additionally, workers required special safety gear.
