What are the four types of nucleotides? The four types of nucelotides are Thymine, Guanine, Cytosine, and Adenine. For RNA, Adenine is replaced with Uracil, which is a smaller nucleotide of sorts. The four nucleotidâ¦es pair as Thymine and Adenine (or Uracil in RNA), and Guanine or Cytosine.
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code. Similar to the way the order of letters in the alphabet can be used to form a word, the order of nitrogen bases in a DNA sequence forms genes, which in the language of the cell, tells cells how to make proteins.
