Nitrogenous bases with one ring are called pyrimidines. To help yourself remember this, use the nitrogenous bases A,C,G,T and the number set 2121. Write these two sets one above the other: A C G T/2121. The numbers underneath

letters correspond to the number of rings each base has, so A has 2 rings, and C has 1 ring, etc. You can then use the phrase, CY (c) and THY (t) are PY (pyrimidines) to remember which is which.

Pyrimidines are nucleotides that have a single ring as their nitrogen base. The two pyrimidines are Cytosine and Thymine.

How are the structures of purines and pyrimidines different?

The main chemical structure difference in purines and pyrimidines is purines have a 5 sided C and N based ring as well as a 6 sided C and N based ring structure. Pyrimidines only have the 6 sided C and N based ring structure, also uracil(unmethylated) replaces thymine(methylated) as a pyrimidine in RNA.
