Human DNA is a thing of wonder, and as human, we are 99.9% similar to every other human in the world. DNA is in genes, and genes are on chromosomes. DNA is composed of four amino acids, which are adenine, guanine, thymine, and cytosine. Take the practice test below and see just how much you remember from chapter 10, 11, 12, and 13.
