Answer:
Inheritance/Evolution (1800s)
By now, the stories of Charles Darwin’s finches, Gregor Mendel’s peas, and Alfred Wallace’s wide traveling naturalist studies have become common lore both in and outside the world of biological sciences. But their long reaching conclusions helped to spur the explosion of growth in the area of biology for the last 170 years. And while it would take the discovery of DNA in the 1950s to sow the seeds of genetic evolutionary studies, we all owe a debt to these naturalist founders who laid the groundwork for many of the things we now take for granted while conducting our research.
Antibiotics (1928)
Alexander Fleming wasn’t setting out in 1928 to revolutionize biological science when he discovered that something in Penicillium mold spores was able to kill staphylococcal bacteria in a petri dish. As is often the case in science, discoveries make remarkable impacts on research that are totally unrelated to the field they were created to help. Fleming was just trying to find a way to prevent anaerobic infections from being so deadly, not looking to find the world’s first antibiotic. But along the way, the discovery of antibiotics have been utilized in innumerable research, as selection tools in transformation and cell culture, as well as a host of other fields and studies.
Gel Electrophoresis (1931)
It’s difficult to imagine any of my labs without the ever-present bench of gel rigs, either humming with the sound of electrical current, dutifully separating proteins, DNA or RNA; or sitting vacant and patiently waiting for another agarose or acrylamide gel. It is just as remarkable to realize that electrophoresis, as we know it, was discovered in 1931 by Arne Tiselius and even earlier work was done in the early 1800s that provided the groundwork for the Tiselius apparatus to differentiate between proteins. But it wasn’t until the 1940s that scientists started using gel matrices to separate compounds into discrete bands. And it wasn’t until the 1960s that gel electrophoresis would really be used to start identifying DNA and other biological molecules that would give birth to the field of molecular biology.
HeLa Cell Discovery (1951)
The cervical cancer cells that were taken from Henrietta Lacks before she died in 1951 have become a benchmark in the history of cancer research and knowledge. The immortal HeLa cells made medical research easier, more robust and repeatable. The cell line is what allowed for the creation of Salk’s first polio vaccine in 1952. Since its discovery, there have been over 11,000 patents created involving the HeLa cells. It is safe to say that without Henrietta’s cells, a great body of research would have been slower and biomedical advancements a great deal more ponderous.
