Pyrimidines have a single ring and are part of the basic building blocks for RNA and DNA.
Purines possess a 5 carbon ring attached to a 6 carbon ring, while pyrimidines have one 6 carbon ring.
A pyrimidine ring and an imidazole ring.
Purines because purines have two rings where as pyrimidines have only one ring.
Thymine is a single-ringed nitrogenous base.
Thymine and cytosine are two nitrogen bases found in DNA. DNA is composed of thousands of nucleotides which are composed of one of four nitrogen bases. Both of these nitrogen bases are also pyrimidines, or they have one ring like structure See related link for more info on thymine, cytosine and pyrimidines.
Purines and pyrimidines are nitrogen bases found in DNA and RNA .They are nitrogen containing heterocyclic compounds .Purines are large double ringed while pyrimidines are small single ringed .

Pyrimidines have a single ring in their molecule.
A pyrimidine ring and an imidazole ring.
Purines because purines have two rings where as pyrimidines have only one ring.
Purines and pyrimidines are the building blocks of nucleic acids. The difference between purines and pyrimidines is in the number of carbon-rings present. Pyrimidines contain one carbon-ring while purines have two.
These rings are known as pyrimidines.
The large bases that have two carbon-nitrogen rings are called purines.

Both of these nitrogen bases are also pyrimidines, or they have one ring like structure See related link for more info on thymine, cytosine and pyrimidines.
There are three nucleobases in nucleic acids that are considered pyrimidines or pyrimidine derivatives. Uracil, cytosine, and thymine are the three pyrimidines.
Cytosine, uracil and thymine are the three pyrimidines.
