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.
There are four different DNA nucleotides, each defined by a specific nitrogenous base: adenine (often abbreviated A in science writing), thymine (abbreviated T), guanine (abbreviated G), and cytosine (abbreviated C) (Figure 2).
