Question

The mice infected with the R strain of the bacterium dies, but when infected with the S strain, they do not die.

(a) False

(b) True

The question was posed to me in an international level competition.

I'd like to ask this question from The Search for Genetic Material topic in chapter Molecular Basis of Inheritance of Biology – Class 12

Answer 1

Right option is (a) False

Easy explanation: The S strain produced by the bacterium is said to be the virulent strain. The mice infected with the S strain will die due to its virulent nature. Whereas, the one infected with the R strain doesn’t die due to its avirulent.

                     Mice -> S strain -> Death

                     Mice -> R strain -> Alive
