A purine base that pairs with cytosine?
guanine
What is the Purine base that always pairs with the cytosine?
guanine
Does Complementary base pairing always pairs a purine with a pyrimidine?
Yes. Adenine+Guanine, or Cytosine+Thymine; each is a pyrimidine/purine pair.
Can base c ever pair with t?
Cytosine should not ever pair with thymine, for two major reasons: Cytosine and thymine are both pyrimidines, meaning they contain a single sugar, whereas adenine and guanine are purine and contain a two-ringed sugar. If cytosine were to pair with thymine (or another cytosine) it would throw off the shape of the DNA double helix. Cytosine wants to form three hydrogen bonds, and thymine can only form two. Thus, under normal circumstances, cytosine will never be paired with thymine.
What is the symbol for purine?
The symbol for purines (Guanine / Adenine) is "R" and for pyrimidines (Cytosine / Thymine) is "Y".
A purine base that pairs with cytosine?
guanine
What are purine base in DNA that bonds to cytosine?
guanine
What is the Purine base that always pairs with the cytosine?
guanine
Purine base that always pairs up with cytosine?
Guanine
How are four bases paired in a molecule DNA?
Adenine(purine)=========thymine(pyrimidine)Guanine(purine)----------------cytosine(pyrimidine)
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!
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).
Does Complementary base pairing always pairs a purine with a pyrimidine?
Yes. Adenine+Guanine, or Cytosine+Thymine; each is a pyrimidine/purine pair.

Thus, under normal circumstances, cytosine will never be paired with thymine.
Pyrimidine base found in DNA and RNA?
Cytosine is the pyrimidine that bonds to the purine Guanine in both DNA and Rna.
What base does cytosine base-pair with?
Cytosine, a pyrimidine (sugar) base, pairs with Guanine, a purine (nitrogen) base.
What is the symbol for purine?
The symbol for purines (Guanine / Adenine) is "R" and for pyrimidines (Cytosine / Thymine) is "Y".
