Before I get to the good stuff, I wanted to quickly upload this tut on something that kids in school could use for their science products. Here is a simple, but fun lesson on how to draw DNA, step by step. I'm sure all of you know that DNA is your genetic makeup and it is what makes you, you. Now, your DNA consists of four chemical bases and they are; Adenine (A), Guanine (G), Cytosine (C), and Thymine (T). If you are studying DNA in Science class I'm sure you will learn more information as your teacher will be going over what DNA is all about.
