DNA Duplication

        When DNA divides it does some really weird things. DNA is made of nucleotides that are made of these components: sugar, phosphate and a base. There are four bases called adenine, thymine, guanine, and cytosine. Adenine and thymine matcth up like puzzle peices and it is the same way with guanine and cytosine. When you look at DNA you can see a twisted ladder shape(DNA is to small to see so some models may show the shape). When DNA splits and duplicates it unzips itself down the middle. Then they make another helix out of protiens to connect with the next helix. They join up and we have two DNA molecules.
