Question

What were the techniques used to stablish DNA as a genetic material?

Answer 1

Hershey and Chase did two experiments to prove that DNA is the carrier of the genetic information. First, they grew phages (viruses which infect bacteria) in a medium containing radioactive sulphur (35S). This marked all the proteins of the phage (the hull) radioactive. They then used this phage to infect bacteria.
