What do humans and bacteria have in common?
A genetic code , encoded into DNA usually runs every aspect of an organism’s life, either through directly producing proteins or by creating enzymes which regulate other chemical reactions. The genetic code is very nearly universal, and the vast majority of it is common to both bacteria and humans.
How are bacteria useful to us?
Some bacteria are good for you, including the bacteria in your digestive system, or gut. These bacteria help to break down food and keep you healthy . Other good bacteria can produce oxygen are used to create antibiotics. Bacteria are used in food production to make yogurt and fermented foods.
