They are the nitrogen bases that are attached to RNA and DNA. In DNA, adenine and guanine are purines and thymine and cytosine are pyrimidines. In RNA, thymine is replaced by pyrimidine uracil.

The purines in DNA are adenine and guanine, the same as in RNA. The pyrimidines in DNA are cytosine and thymine; in RNA, they are cytosine and uracil.

What is transversion mutation?
in this a purine base is substitued in place or pyrimidine and a pyrimidine is substitued in place of purine
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).
How many adenine bases are there if you have 112 purine bases and 64 cytosine bases?
There is no way to tell, since adenine is a purine base, but not the only one. Cytosine is a pyrimidine base. So it can be anything from 0 to 112!
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 DNA and RNA?
Cytosine is the pyrimidine that bonds to the purine Guanine in both DNA and Rna.
How are four bases paired in a molecule DNA?
Adenine(purine)=========thymine(pyrimidine)Guanine(purine)----------------cytosine(pyrimidine)
What bond holds purine bases and pyrimidine bases together?
ATGACGT
When purine base only pairs with a pyrimidine?
when a purine base only pairs with a pyrimidine
What is transversion mutation?
in this a purine base is substitued in place or pyrimidine and a pyrimidine is substitued in place of purine
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).
How many adenine bases are there if you have 112 purine bases and 64 cytosine bases?
There is no way to tell, since adenine is a purine base, but not the only one. Cytosine is a pyrimidine base. So it can be anything from 0 to 112!
Is nitrogen a 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.
A particular sequence of parent DNA has five purine bases and two pyrimidine bases. According to base pairing rules, which of the following sequences could be formed during replication?
Chargaff's rule means that there should be the same number of purine and pyrimidine bases in DNA. The base-pairing rules mean that A always pairs with T, and G always pairs with C ie. a purine always pairs with a pyrimidine, so there must be the same number of both proving Chargaff's rule.
Does Complementary base pairing always pairs a purine with a pyrimidine?
Yes. Adenine+Guanine, or Cytosine+Thymine; each is a pyrimidine/purine pair.
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 DNA and RNA?
Cytosine is the pyrimidine that bonds to the purine Guanine in both DNA and Rna.
Constituents of DNA?
Components of DNA include purine bases and pyrimidine bases (which, when combined, make up base pairs), deoyribose sugars, nucleotides and nucleosides.
