Jun 29, 2015 · The announcement of the discovery of messenger RNA (mRNA) and the cracking of the genetic code took place within weeks of each other in a climax of scientific excitement during the summer of 1961. Although mRNA is of decisive importance to our understanding of gene function, no Nobel Prize was awarded for its discovery. DNA was first isolated by the Swiss physician Friedrich Miescher who, in 1869, discovered a microscopic substance in the pus of discarded surgical bandages. As it resided in the nuclei of cells, he called it "nuclein". The DNA of the virus was tagged with radioactive phosphorus in one experiment, and this ended up in the pellet. The protein shell of the virus was tagged with radioactive sulphur, and this ended up in the supernatant. The heavier bacterial cells formed the pellet, so Hershey and Chase knew that DNA was the genetic material of the virus, as the ... The Hershey-Chase experiments. In their now-legendary experiments, Hershey and Chase studied bacteriophage, or viruses that attack bacteria.
