think about it........
our bodies are made by DNA and RNA. These two chemicals make us who we are. Our hair color, skin color, personality, height, weight, etc. DNA is made up by Guanine, Thymine, Adenine, and Cytosine. These 4 chemicals in specific order code for who we are. RNA polymerase reads this code and translates it into our character and personality. DNA is the blueprints to our bodies. Now think about a computer. Computers are dictated by codes. The codes are read over in the computer to determine programs and the way it works. My point is that we our similar to computers. Both computers and humans use code to determine traits and programs.
