All biological cells store their genetic information in the form of DNA. DNA is an abbreviation of deoxyribonucleic acid. DNA molecules determine the types of protein synthesised within the cell. Eukaryotes store their DNA in their nucleus and prokaryotes store their DNA in their nucleoid.
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.lthough most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA. This genetic material is known as mitochondrial DNA or mtDNA. Mitochondria (illustration) are structures within cells that convert the energy from food into a form that cells can use.
