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.

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

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

Assertion (A): In Griffith's experiment, the dead R strain bacteria was capable of causing the transformation of the live S-strain bacteria. Reason(R): The S-strain is non-virulent strain.

How did Griffith explain the transformation of R-strain (non-virulent) Bacteria into S-strain (virulent)?

Recall the experiments done by Frederick Griffith. Where DNA was speculated to be the genetic material. If RNA, instead of DNA was the genetic material, would the heat killed strain of pneumococcus have transformed the R - strain into virulent strain ? Explain ?

Recell the experiments done by frederick Griffith, Avery, MacLeod and McCarty, where DNA was speculated to be the genatic material. If RNA , instead of DNA was the genetic meterial, would the heat killed strain of pneumoccus have transformed the R-strain into virulent strani? Explain.
