Nucleotide

Nucleotide in short discussion:

The main structural unit of DNA is the nucleotide. A nucleotide is made with the combinations of a sugar molecule (either ribose in RNA or Deoxyribose in DNA) linked to a phosphate group and a nitrogen containing base. In DNA the bases are Adenine (A), Guanine(G), Cytosine(C) and Thymine (T). In RNA the base Thymine (T) is replaced with Uracil (U).
