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

How many adenine bases are there if you have 112 purine bases and 64 cytosine bases?

If there are 112 purine bases in total, and adenine (A) is a type of purine base, and cytosine (C) is not, then the number of adenine bases can be calculated by subtracting the number of cytosine bases from the total purine bases. Therefore, there would be 48 adenine bases in this scenario (112 purine bases - 64 cytosine bases = 48 adenine bases).


Two nitrogenous bases known as purines are?

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.


What are pyrimadines an purines?

Pyrimidines (cytosine, thymine, uracil) are nitrogenous bases with a single-ring structure found in DNA and RNA. Purines (adenine, guanine) are nitrogenous bases with a double-ring structure also found in DNA and RNA. They form the building blocks for nucleic acids.


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.


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.
