DNA
DNA or deoxyribonucleic acid is where the hertiable genetic information is stored. DNA is a type of nucleic acid and is made up of nucleotides and polymers.
Structure: The structure of this double helix DNA is two strands of nucleotide wound around each other. The proper name for this shape is a "double-helix." The outsides are called sugar phosphate backbones. The inside is the four nitrogenous bases. These bases are paired together: Adenine (A) is paired with Thymine (T) and Cytosine (C) is with Guanine (G).
