The two purines are adenine and guanine. The two pyrimidines are thymine and cytosine. Uracil (only in RNA) is also a pyrimidine.
Adenine and Guanine are the two classes of nitrogenous bases that belong to purines.
The two nitrogenous bases that are purines are adenine and guanine.
Four, out of whish 2 purines and two pyremidines
The two classes of nitrogenous bases are purines and pyrimidines. Purines include adenine and guanine, while pyrimidines include cytosine, thymine, and uracil.
the nitrogenous base which has double ring structure is purine.it consist two bases adenine and guanine;

Purines and Pyrimidines
Purines. They are one of the two types of nitrogenous bases found in DNA and RNA, and they consist of a double-ring structure. Adenine and guanine are examples of purines.
Nitrogenous bases are categorized into two groups: pyrimidines (cytosine, thymine, and uracil) and purines (adenine and guanine).
The two purines in DNA are adenine (A) and guanine (G). They are nitrogenous bases that form complementary base pairs with their corresponding pyrimidines (thymine and cytosine) during DNA replication and transcription.
The two nitrogenous bases known as purines are adenine and guanine. They are found in DNA and RNA molecules, where they pair with thymine and cytosine (in DNA) or uracil and cytosine (in RNA), respectively.
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.
