Adenine and guanine are called purines because they are composed of the 2-ringed heterocyclic aromatic organic compound purine.
Uracil, cytosine, or thymine
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.
Cytosine and thymine. one is a double ring sugar while the other is a single ring suagr. They are complemetarily paired with purines.
Pyrimidines, such as cytosine, thymine, and uracil.
Thymine and cytosine are nucleobases that are part of a group of molecules known as pyrimidines. Pyrimidines are a type of nitrogenous base found in nucleic acids like DNA and RNA, and they are essential for genetic information storage and transmission in living organisms.
Cytosine, thymine and uracil are the pyrimidines in animal usage.
The pyrimidines are a class of nitrogenous bases that includes cytosine, thymine, and uracil. These bases are found in nucleic acids like DNA and RNA, where they pair with complementary purines to form the building blocks of genetic information.
Thymine and cytosine.
Cytosine, uracil and thymine are the three pyrimidines.
Pyrimidines are the single ringed structures-Cytosine and ThyminePurines are the double ringed structures- Adenine and Guanine.

pyrimidines
Thymine and Cytosine :)
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.
