what monacrule makes up dna
Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.
DNA's Chemical Makeup. As already mentioned in the previous section, DNA is made up of specific molecules including sugars, phosphate groups and its functional 'bases'. This section will outline the primary chemical makeups of these particular molecules.
