What are the purine bases and pyrimidine bases?

The purine bases are adenine and guanine, while the pyrimidine bases are cytosine, thymine, and uracil. Purine bases have a double-ring structure, while pyrimidine bases have a single-ring structure. These nitrogenous bases are essential components of DNA and RNA molecules.


What are DNA and RNA similarities?

DNA and RNA contain purine and pyrimidine nitrogenous bases, one benzoic acid radicle and one pentose.


What are the three pyrimidine bases?

There are 2 groups of nitrogen bases. These are Pyrimidine and Purine. In the Purine group, there are Adenine and Guanine, In the Pyrimidine group, there are Cytosine, Thymine(replaced by Uracil in RNA).


What bond holds purine bases and pyrimidine bases together?

Hydrogen bonds hold purine bases (adenine and guanine) and pyrimidine bases (cytosine, thymine, and uracil) together in DNA and RNA molecules. These hydrogen bonds form between specific pairs of bases, with adenine always pairing with thymine (or uracil in RNA) and guanine always pairing with cytosine.


Which purine or pyrimidine bases are not present in the messanger RNA m-RNA is it adenine or guanine or cytosine or thymine or uracil?

thyamine isn't present in mRNA its place is taken by uracil


Nitrogenous bases of the purine type?

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


Pyrimidine base found in RNA but not DNA?

Uracil is the pyrimidine base found in RNA that is not present in DNA. Uracil pairs with adenine in RNA during transcription and translation processes.


What does the term pyrimidine mean?

It is the basis of several important biochemical substances. Some of them are fundamental constituents of nucleic acids. The pyrimidines include the bases of some of the components of DNA and RNA, thymine, uracil and cytosine. It is an organic compound with a very strong odor.
