Vaccines work by training the immune system to recognize and combat pathogens, either viruses or bacteria. In order to do this, certain molecules from the pathogen need to be introduced into the body to trigger an immune response. These molecules are called antigens, and they’re present on all viruses and bacteria. Memory cells are then formed to remember the same pathogen for faster antibody production in future infections. Vaccinations increase the level of circulating antibodies against a certain antigen. Antibodies are produced by a type of white blood cell (lymphocyte) called B cells.

As per the demonstration of Griffith and Avery, it can be concluded that the given experiment finding supports hypothesis III, i.e. genetic material or transforming substance is DNA.

<h3>What is Genetic material?</h3>

Genetic material may be defined as any substance found in the cells of plants, animals, microbial or other origins that hold genetic information and that departs it from one generation to the next.

In 1944, Avery and others concluded that the transforming material was pure DNA, not protein or RNA.

These investigators found that DNA extracted from a virulent strain of the bacterium Pneumococcus genetically transformed an avirulent strain of the organism into a virulent form.

Therefore, as per the demonstration of Griffith and Avery, it can be concluded that the given experiment finding supports hypothesis III, i.e. genetic material or transforming substance is DNA.
