Fact of the Day: Four Letters

While DNA makes up every living thing on Earth, there are only four building blocks. Everything from animals, plants, and bacteria all have DNA which contains adenine, thymine, guanine, and cytosine. They are commonly called "letters" and they combine together to form the double helix shape.
