What is DNA made of?

The rungs (ladder steps) of DNA come off sugar molecules called bases. There are four bases called adenine (A), guanine (G), cytosine (C), and thymine (T). Each rung is made of two-linked bases. Only (A) and (T) can link together and only (G) and (C) can link together. Adenine and Guanine are purines. Purines are double ringed structures. Cytosine and Thymine are single ringed structures and are known as pyramidines.

The basic chemicals found in DNA are carbon, nitrogen, hydrogen, oxygen and phosphorous.

DNA is in every cell in your body. Technically, you could clone a animal with a strand of hair, and a human by his sweat.

A human can get their DNA analyzed to find out about their past. This technology is only about 12 years old, be a pioneer in this technology. Get your DNA test done at
