Recall the experiment done by Frederick Griffith. If RNA, instead of DNA was the genetic material, would the heat killed strain of Pneumonococcus have transformed the R-strain into virulent strain? Explain your answer.

Text Solution

Verified by Experts

RNA is more labile and prone to degradation (owing to the presence of 2' OH group in its ribose). Hence heat-killed S-strain may not have retained its ability to transform the R-strain into virulent form if RNA was its genetic material
