How do purines differ from pyrimidines?

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.


What is Thymine and cytosine also called?

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.


What are the two classes of nitrogen bases?

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.


Why are thymine and cytosine are called pyrimidines?

Thymine and cytosine are called pyrimidines due to their chemical structure, which includes a six-membered nitrogen-containing ring with two nitrogen atoms. Pyrimidines are one of the two main types of nitrogenous bases found in DNA and RNA, the other being purines.


Which one is purines and pyrimidines are bigger?

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.
