Transforming Principle

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.

Consider the following four statements (a-d) and select the options which includes all the correct ones only :- (a) Transforming principle explained by Griffith was later identified as DNA (b) Histones are rich in acidic amino acids lysines and arginines. (c) In RNA, every nucleotide has -OH group present at 2-position of ribose. (d) In a ds DNA the two chains have antiparallel polarity.

(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?

Describe the transformation principle proposed by Griffith.
