Recall the experiments done by Frederick | Class 12 Biology Chapter Molecular Basis of Inheritance, Molecular Basis of Inheritance NCERT Solutions

Question:

Recall the experiments done by Frederick Griffith, Avery, MacLeod and McCarty, 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.

Answer:

RNA is more liable and prone to degradation like owing to the presence of 2’OH group in its ribose. Hence, heat killed S- strain may not have regain its ability to transform the R- strain into the virulent form if it was having RNA in the form of genetic material.
