Biotechnology has been in use since 1919, and its first application was in a DNA recombination experiment with bacteria. Today, biotechnology has been applied in the manufacture of medicines, medical devices, diagnostic tools, biomaterials, and food production.
Each cell in your body contains about 2 meters of DNA. If the whole DNA in one person was laid end to end in a straight line, it would measure up to 200 billion kilometres that is more than a thousand times the distance from the earth to the sun.
