Select the correct option for the $R$ strain of bacteria.

Analyze the following experimental steps performed by Frederick Griffith:
$I - R$ strain $\rightarrow$ injected into mice
$II - S$ strain $\rightarrow$ injected into mice
$III - S$ strain (heat-killed) $\rightarrow$ injected into mice
$IV - S$ strain (heat-killed) $+ R$ strain (live) $\rightarrow$ injected into mice
In which of the above stages will the mice remain alive?

In Griffith's experiment,which new bacteria were recovered from the dead mice?

Who performed the famous "Replica Plating Experiment"?

Which of the following viruses contains $RNA$ as its genetic material?

The result of which of the following reaction experiments carried out by Avery et al. on $Streptococcus \text{ } pneumoniae$ has proved conclusively that $DNA$ is the genetic material?
