adenine and cytosine
The name of the double ring nitrogenous bases found in nucleotides is a double-helix. Nucleotides are the building blocks of nucleic acids such as RNA and DNA.
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.
The nitrogenous substances A and G are purines (double rings).
The large bases that have two carbon-nitrogen rings are called purines.
adenine----The four nitrogenous bases that comprise DNA are adenine, guanine, thymine, and cytosine. there are four kinds of nitrogenous bases in dna. two of the nitrogenous bases, adenine and guanine,belong to a group of compounds known as purines. the remaining two bases, cytosine and thymine, are know as pyrimidines. Adenine pairs up with thymine, and cytosine pairs up with guanine. Humans also use a fifth base in RNA called uracil. In the case of RNA, thymine is replaced by uracil and other three bases remains the same. All of these bases are attached to the sugar and phosphate. The double helix maintains a constant width because purines always face pyrimidines in the complementary A-T and G-C pairs. And they are all connected by a phosphorous base. A-T; G-C The phosphorous base can be broken for DNA replication purposes.
Adenine and Guanine belong to the class of nitrogenous bases called purines. They are characterized by a double-ring structure that includes both a six-membered ring and a five-membered ring. These purine bases play a crucial role in the structure of DNA and RNA molecules.
Guanine and Adenosine
Purines and pyrimidines.purines contain adenine,guanine,hypoxanthine and xanthine.pyrimidines contain uracil,thymine,cytosine,orotic acid
Four, out of whish 2 purines and two pyremidines
The two purines are adenine and guanine. The two pyrimidines are thymine and cytosine. Uracil (only in RNA) is also a pyrimidine.

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.
The two DNA bases Adenin and Guanine belong to the group called Purines.
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.
Plato users D. Thymine, cytosine
Purines, Pryimidine and Nucleotide are the subunits of DNA.
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.
