Summary Introduction

To explain:

The process by which alteration in the genetic makeup of live type IIR bacteria was performed by heat killed type IIIS bacteria.

Introduction:

In his experiment Griffith took heat killed type IIIS bacteria and mixed it with living type IIR bacteria, out of which type IIIS was virulent while type IIR was non virulent. After injecting it into the mice, the mice died of pneumonia. He observed live type IIIS bacteria. By observing the result he determined transforming principle is responsible in the transformation of IIR bacteria into type IIIS bacteria and making them virulent.
