The Hershey–Chase experiments were a series of experiments conducted in 1952 by Alfred Hershey and Martha Chase that helped to confirm that DNA is genetic material. While DNA had been known to biologists since 1869, many scientists still assumed at the time that proteins carried the information for … See more In the early twentieth century, biologists thought that proteins carried genetic information. This was based on the belief that proteins were more complex than DNA.
