Cytosine and thymine. one is a double ring sugar while the other is a single ring suagr. They are complemetarily paired with purines.
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.
Purines because purines have two rings where as pyrimidines have only one ring.
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 and are part of the basic building blocks for RNA and DNA.
Uracil, cytosine, or thymine
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.
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.
Adenine and Guanine are purines, and Thymine and Cytosine are pyrimidines.
There are three nucleobases in nucleic acids that are considered pyrimidines or pyrimidine derivatives. Uracil, cytosine, and thymine are the three pyrimidines.
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.
Purines because purines have two rings where as pyrimidines have only one ring.
Cytosine, thymine and uracil are the pyrimidines in animal usage.
Thymine & Adnine
Pyrimidines are the single ringed structures-Cytosine and ThyminePurines are the double ringed structures- Adenine and Guanine.
Remember: Pure As Gold--- purines are arginine and guanine so, pyrimidines must be thymine and cytosine FREEGAZA.ORG
The two classes of nitrogen bases are purines and pyrimidines. Purines include adenine and guanine, which have a double-ring structure, while pyrimidines include cytosine, thymine, and uracil, which have a single-ring structure.
