(a) Describe the various steps of Griffith's experiment that led to the conclusion of the 'Transforming Principle'.
(b) How did the chemical nature of the 'Transforming Principle' get established ?

Who revealed biochemical nature of the transforming principle?

Describe Griffith's experiment of transformation.

The transforming principal in Griffith's experiment was established

Describe the transformation principle proposed by Griffith.

(a) Explain Griffith's series of experiments where he witnessed transformation in bacteria he worked with. (b) Name the scientists responsible for determining the biochemical nature of "transforming principle" in Griffith's experiments. What did they prove?

Assertion : In Griffith's experiment, a mixture of heat-killed virulent bacteria R and live non - virulent bacteria S, lead to the death of mice. Reason : 'Transforming principle' got transferred from heat -killed R strain and made it virulent.

(a) Explain with the help of Griffith's experiment how the seach for genetic material was conducted and what was the conclusion drawn ? (b) How did Macleod,Mc Carty and Avery establish the Bio-Chemical nature of the so called "genetic material" identified by Griffith in his experiment.
