In DNA cytosine and thymine are pyrimidine derivatives. Uracil (in RNA) is also a pyrimidine. Pyrimidines have only one 6-membered ring.

Two nitrogenous bases known as purines are?
adenine, and guanine are purines Cytosine and thymine are pyrimidines. by:mj
How many rings do adenine and guanine have?
Adenine and guanine molecules are two of the four nitrogenous bases that help make up the structure of DNA. They are also known as "purine" bases because they have a double ring structure. The purine bases are extremely important in DNA formation and they specifically pair up with the other two nitrogenous bases, known as the "pyrimidine" bases. Adenine molecules will always pair with thymine molecules and guanine molecules will always pair with cytosine.
How are the four nucleotides different?
A nucleotide is composed of a nucleobase (nitrogenous base), a five-carbon sugar , and one phosphate group.They differ in their nitrogenous bases - they can either contain a purine(big) or a pyrimidine(small) base. In DNA, the purine bases are adenine and guanine, while the pyrimidines are thymine and cytosine. RNA uses uracil in place of thymine
What is the name of the double ring nitrogenous bases found in nucleotides?
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.
Why does the order of nitrogen bases matter?
if the order of nitrogenous bases is mixed up the chemical reactions will be the wrong result. they are set in a specific order for a reason Adenine pairs with Thymine(Double bond) Guanine pairs with Cytosine (Triple Bond) A & G are purine bases and T & C are pyrimidine bases. this is the order
What comprises a purine?
Double ringed nitrogenous bases of DNA and RNA including adenine and guanine.
What type of bases do adenine and guanine have?
Purine bases because they are double-ringed.
What are DNA and RNA similarities?
DNA and RNA contain purine and pyrimidine nitrogenous bases, one benzoic acid radicle and one pentose.
Which nitrogenous base is composed of two rings?
the nitrogenous base which has double ring structure is purine.it consist two bases adenine and guanine;

What type of bonding do the nitrogenous bases form?
covalent bonding
What are the parts of a DNA moleclue?
The parts of DNA molecule are nucleotide, bases, and the hydrogen bonds. The nucleotide contains a pentose sugar, phosphate group, and nitrogenous bases. Bases contain pyrimidine and purine and the hydrogen bonds holds the chains of nucleotides.

What are the elements of a nitrogenous base?
A basic compound that contains nitrogen, such as a purine or pyrimidine. A basic compound that contains nitrogen, such as a purine or pyrimidine.
What type of bonds form between two nitrogenous bases?
covalent
