DNA

                What is DNA? People think of DNA as a twisted ladder. But DNA makes up your cells. You might think something that holds so much would be incredibly complicated and large. But, DNA is actually small and simple.

                What is DNA made of? DNA is made of an alternating phosphate and sugar molecules in a linked chain. The rungs of DNA come off sugar molecules and are called bases. There are four different types of bases. They are adenine, thymine, guanine, and cytosine or A, T, G, and C. Each rung is made of two linked bases. Only certain bases can link together (A to T and G to C).

                DNA is in every cell of your body. So, you could get DNA from hair, skin, blood, etc. With just a strand of hair you could clone an animal. But, most DNA extraction on humans comes from sampled of blood. The blood usually comes from the arm. You would get a shot which comes with out with a blood sample. With the blood samples scientist can do all sorts of things.

                Over all DNA makes up cells which we use to clone.
