Define transformation in Griffith's experiment. Discuss how it helps in the identification of DNA as the genetic material.

Explanation

### Step-by-Step Text Solution

**Step 1: Define Transformation in Griffith's Experiment**
Transformation in Griffith's experiment refers to the process by which a non-virulent strain of bacteria takes up genetic material (DNA) from a dead virulent strain, resulting in a change in its genetic constitution. This change allows the non-virulent bacteria to acquire the ability to cause disease.

**Step 2: Overview of Griffith's Experiment**
In the experiment, Griffith used two strains of Streptococcus pneumoniae: a virulent strain (smooth, S strain) that caused disease and a non-virulent strain (rough, R strain) that did not. He injected mice with these strains to observe the effects.
