A pyrimidine ring and an imidazole ring.
Purines because purines have two rings where as pyrimidines have only one ring.
Pyrimidines have a single ring and are part of the basic building blocks for RNA and DNA.
Pyrimidines have a single ring structure, while purines consist of two fused rings. Pyrimidines include cytosine, thymine, and uracil, whereas purines include adenine and guanine. This structural difference is fundamental to the composition of nucleotides in nucleic acids like DNA and RNA.
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.

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 because purines have two rings where as pyrimidines have only one ring.
Pyrimidines have a single ring and are part of the basic building blocks for RNA and DNA.
These rings are known as pyrimidines.
Pyrimidines have a single ring structure, while purines consist of two fused rings. Pyrimidines include cytosine, thymine, and uracil, whereas purines include adenine and guanine. This structural difference is fundamental to the composition of nucleotides in nucleic acids like DNA and RNA.
The large bases that have two carbon-nitrogen rings are called purines.
There are two purines (adenine and guanine) and two pyrimidines (cytosine and thymine) present in the DNA molecule.
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.
