Joan Folkes
Joan P. Folkes (born 1927) was a scientist who was nominated for the Nobel Prize in chemistry in 1956.[1] Along with Ernest Gale,[2]: 413 she demonstrated that nucleic acids have an organizing or controlling role in protein synthesis. In his 2005 book, Hans-Jörg Rheinberger discussed the work of Folkes and Gale and how they revealed a connection between the levels of nucleic acids in cells and the rate that proteins were made.[3]: 162
Folkes and Gale were also the first to demonstrate cell-free protein production in a crude cell extract.[4][5] During this work, they broke open cells of Staphylococcus aureus by vibration and the demonstrated that a template chemical existed, now recognized as DNA, that enables the production of proteins even in the absence of living cells.[6][7] At the time, they called the chemical 'incorporation factors'[8] because they were fragments of nucleic acids that encouraged amino acids to form into proteins.[9]
Career
[edit]She worked at the Medical Research Council Unit of Chemical Microbiology in Cambridge, England.[2]: 389
