Hershey and chase performed an experiment in order to determine how bacteriophages infect bacteria and discovered that DNA is the genetic material.
<h3>What is DNA?</h3>
This is referred to as deoxyribonucleic acid and is the genetic material of living organisms .
Hershey and chase performed an experiment using bacteriophages which contains protein and DNA by infecting it with bacteria and it was observed that DNA enters the host bacterial cell, but most of their protein does not.
This therefore means that DNA is regarded as the hereditary material.
The respiratory system and the circulatory system function together as a “coupled unit” delivering the body's oxygen and nutrients and taking away carbon dioxide and wastes to maintain homeostasis.
