Every living thing possesses DNA, from plants to animals, bacteria, and even viruses, which were formerly thought to be "nonliving." The most essential thing is that we humans have it. DNA is an abbreviation for deoxyribonucleic acid. And, while every living thing has DNA, the content of your DNA distinguishes you from others.
Many people believe that DNA was discovered in the 1950s by American biologist James Watson and English physicist Francis Crick. This is not the situation in reality. Rather, Swiss chemist Friedrich Miescher discovered DNA in the late 1860s.
