Summary Introduction

To review:

The circumstantial evidence in Griffith’s experiment of 1928 that indicated DNA (deoxyribonucleic acid) to be the genetic material.

Introduction:

Griffith conducted experiments on mice utilizing the bacteria Streptococcus pneumoniae in an attempt to discover a method to find a vaccine against this pneumonia-causing bacteria. He used two strains, rough strain (RII) and smooth strain (SIII). The R strain was the avirulent strain, while the S strain was the virulent strain and caused pneumonia.
