Hershey and Chase Experiment In 1953‚ Alfred Hershey and Martha Chase confirmed DNA’s preeminent role in genetics by demonstrating that DNA is the genetic material of a virus called phage T2. The phage‚ which infects E. coli‚ consists of a head‚ sheath‚ tail‚ and base plate made of different proteins. DNA is packaged within the head of the virus. When T2 comes in contact with E. coli‚ the phage attaches to the bacterium by its tail. Next‚ the phage injects genetic material into the cell. The genetic
