Define transformation in Griffith's experiment. Discuss how it helps in the identification of DNA as the genetic material.

Why DNA is a primary genetic material?

How is the DNA better genetic material than RNA?

Describe Griffith’s experiment in brief to prove that DNA is a genetic material.

How did Hershey and Chase differentiate between DNA and protein in their experiment while proving that DNA is the genetic material?

How is a key helpful in the identification and classification of an organism?

Recall the experiments done by Frederick Griffith, Avery, MacLeod and McCarty, where DNA was speculated to be the genetic mnaterial. If RNA, instead of DNA was the genetic material, would the heat killed strain of Pneumolcoccus have transformed the R-strain into virulent strain? Explain.

What is the significance of adding proteases at the time of isolation of genetic material (DNA) ?
