$A$ bacterium grown on a medium containing radioactive Sulphur incorporates the radioactivity into:

Which scientist experimentally proved that $DNA$ is the sole genetic material in bacteriophage?

Following representations $P$,$Q$ and $R$ denote few steps of the Griffith Experiment. Identify the correct one$(s)$:
$P. R$ strain $\rightarrow$ Inject into mice $\rightarrow$ Mice die
$Q. S$ strain (Heat killed) $\rightarrow$ Inject into mice $\rightarrow$ Mice die
$R. R$ strain $\rightarrow$ Inject into mice $\rightarrow$ Mice live

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

$A$ molecule that acts as genetic material must fulfill the following criteria,$EXCEPT$:

If $DNA$ contained sulphur instead of phosphorus and proteins contained phosphorus instead of sulfur,what would have been the outcome of Hershey and Chase experiment?
