What happed when heat killed S cells along with live R cells were injected into mice ?

Heat killed S- cells alongwith live R- cells of Diplococcus pneumoniae were injected in mice

Recell the experiments done by frederick Griffith, Avery, MacLeod and McCarty, where DNA was speculated to be the genatic material. If RNA , instead of DNA was the genetic meterial, would the heat killed strain of pneumoccus have transformed the R-strain into virulent strani? Explain.

A solid mixture contains four constituents P, Q, and S. P consists of tiny grains and it is mixed with cement for plastering the walls. Q is a white solid which is recovered on a large scale from sea water by the process of evaporation. R is in the from of tiny particles of a material whose corrosion is called resting. And S is a white solid which is used in making ordinary dry cells. (a) What could P, Q R and S be ? (b) How would you separate a mixture containing P, Q, R and S ?
