Describe Griffith’s experiment for demonstration of DNA as a genetic material with suitable diagram

Griffith's experiment, conducted in 1928 by Frederick Griffith, was a pivotal experiment in the field of genetics that provided strong evidence suggesting that DNA is the genetic material responsible for transmitting hereditary traits. Here's a description of the experiment along with a simplified diagram:

Experiment Description:

1. Preparation of Bacterial Strains: Griffith worked with two strains of the bacterium Streptococcus pneumoniae. One was a virulent (disease-causing) strain called the S strain, which had a smooth appearance due to a polysaccharide capsule that protected it from the host's immune system. The other was a non-virulent (harmless) strain called the R strain, which lacked the capsule and had a rough appearance.

2. Experimental Procedure:

   a. Griffith injected mice with four different combinations of bacterial __________ _________ _____ _____ _________.
