Purines are larger molecules compared to pyrimidines. Purines consist of a six-membered ring fused to a five-membered ring, while pyrimidines are single-ring structures.
Pyrimidines have a single ring and are part of the basic building blocks for RNA and DNA.
Thymine is a single-ringed nitrogenous base.
Pyrimidines (cytosine, thymine, uracil) have a single-ring structure, while purines (adenine, guanine) have a double-ring structure. Purines always pair with pyrimidines in DNA and RNA bases. Additionally, purines are larger molecules compared to pyrimidines.
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.

Pyrimidines have a single ring in their molecule.
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.
Purines are larger molecules compared to pyrimidines. Purines consist of a six-membered ring fused to a five-membered ring, while pyrimidines are single-ring structures.
Pyrimidines have a single ring and are part of the basic building blocks for RNA and DNA.
These rings are known as pyrimidines.
The large bases that have two carbon-nitrogen rings are called purines.
Thymine is a single-ringed nitrogenous base.
Cytosine, uracil and thymine are the three pyrimidines.
Various medications and dietary supplements contains pyrimidines. Pyrimidines are important components to HIV therapeutics, the thiamine vitamin, and the narcotic barbitone.
Adenine and Guanine are purines, and Thymine and Cytosine are pyrimidines.
There are three resonance structures of pyrimidines. These structures involve the delocalization of electrons within the aromatic ring of the molecule, leading to different arrangements of double bonds.
