(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?

The transforming principal in Griffith's experiment was established

The transforming principal in Griffith's experiment was established

(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.

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

(a) Explain Griffith’s series of exeeriments where he witnessed transformatio in bacteria he worked with. (b) Name the scientists responsible for determining the biochemical nature I “transforming principle” in Griffith’s experiments. What did they prove ?

(a) state the central dogma as proposed by francis crick are there any exceptions to it ? Suppport your answer with a reason and an example (b) Explain how the biochemical chraterisation (nature) of Transforming pronciple was determined which was not defined from Griffith 's experiments

In Griffith's transforming principle, if heat-killed S-strain is injected into mice, then :

a) Write the conclusin drawn by Griffith at the end of his experiment with Streptococcus pneumoniae. b) How did O.Avery, C.MacLeod and M. McCarty prove that DNA was the genetic material? Explain.
