Unoxygenated blood from veins enters the right atrium then it goes down to the right ventricle then out through the pulmonary artery to the lungs where it becomes oxygenated blood which then enters the heart through the pulmonary veins and it goes to the left atrium and then is pumped down to the left ventricle and out through the aorta to the arteries where it travels to different organs and becomes deoxygenated and then the cycle repeats itself.

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.
