Choose the correct option for the conclusion of the Hershey-Chase experiment.

Given below are two statements:

Statement I: RNA mutates at a faster rate.

Statement II: Viruses having RNA genome and shorter life span mutate and evolve faster.

In the light of the above statements, choose the correct answer from the options given below:

A bacterial strain $\mathrm{S}$ was heat killed. Another strain $\mathrm{R}$ (living) was taken and mixed with this S strain. This mixture of $\mathrm{S}+\mathrm{R}$ strains were injected into mice. Which of the following are observed by Griffith?

I. The cells of $\mathrm{S}$ strain were dead in dead mice.

II. The bacterial cells without polysaccharide coat are transformed into virulent strain in the injected mice.

II. Griffith could not find living $\mathrm{S}$ strain in the body of dead mice.

IV. Griffith could find living $\mathrm{S}$ strain in the body of dead mice.

The correct combination is:

A student grew virus in three different media containing ${\mathrm{P}}^{32}, {\mathrm{S}}^{35}$ and DNAase separately and allow this virus to attack to E. coli. The series of observation made by the students are as follows:

a) ${\mathrm{P}}^{32}$ labelled phage particles were produced in E. coli.
b) ${\mathrm{S}}^{35}$ containing phage particles were produced E. coli.
c) Phage particles were observed in E. coli.

d) ${\mathrm{P}}^{32}$ was not observed in phage particles produced by E. coli.
e) ${\mathrm{S}}^{35}$ was not observed in phage particles produced by E. coli.

The correct observations are
