Experiments in Search of Genetic Material

The series of experiments done by F. Griffith involved which of the following bacterium:

MacLeod, McCarty and Avery determined that R strain bacteria transforming into S strain bacteria because of:

Experiments of Griffith on mice explained the phenomenon of:

Arrange the following biological discoveries in the correct chronology from the earliest to the latest.
i. British biochemist Frederick Sanger introduces his 'plus and minus' method for DNA sequencing.
ii. American scientists Walter Gilbert and Allan Maxam introduce their method of DNA sequencing using chemical processes to terminate DNA strands.
iii. Swiss physician Friedrich Miescher discovers and isolates DNA
iv. Canadian-American researchers Oswald Avery and Colin Munro MacLeod, along with American geneticist Maclyn McCarty, working on experiments on pneumococcal bacteria, establish that DNA could transform the properties of cells.
v. American biologist James Watson and English physicist Francis Crick discover the double helix when solving the three-dimensional structure of DNA, working from crystallographic data produced by Rosalind Franklin and Maurice Wilkins.

In an experiment, bacteria were infected with ${}^{32}\mathrm{P}$ labelled virus in a ratio of $5:1$. The culture was rigorously shaken followed by centrifugation. Radioactivity was:

Frederick Griffith performed an experiment where mice were killed when injected with a mixture of Heat-Killed $\mathrm{S}$-type Streptococcus $\left(\mathrm{HKS}\right)$ and Live $\mathrm{R}$-type Streptococcus $\left(\mathrm{LRS}\right)$ but not with $\mathrm{HKS}$ or $\mathrm{LRS}$ separately. Mice were killed because
