In their experiments, Hershey and Chase showed that when bacteriophages, which are composed of DNA and protein, infect bacteria, their DNA enters the host bacterial cell, but most of their protein does not. Hershey and Chase and subsequent discoveries all served to prove that DNA is the hereditary material.
How did Hershey and Chase proved that DNA is the genetic material?
Complete answer: Two scientists Alfred Hershey and Martha Chase proved that DNA is a genetic material by working on bacteriophages. … After doing this, they observed that the viruses which were grown in radioactive phosphorus contained radioactive DNA. There was no presence of radioactive protein.
How did Hershey and Chase differentiate?
Hershey and Chase worked with bacteriophage and E. … They used different radioactive isotopes to label DNA and protein coat of the bacteriophage. They grew some bacteriophages on a medium containing radioactive phosphorus (32P) to identify DNA and some on a medium containing radioactive sulphur (35S) to identify protein.
