Adenine pairs with ThymineCytosine pairs with Guanine
No, purines cannot pair with other purines in DNA or RNA. Purines always pair with pyrimidines through complementary base pairing to maintain the double-stranded structure of DNA. In DNA, adenine (a purine) pairs with thymine (a pyrimidine) and guanine (a purine) pairs with cytosine (a pyrimidine).
Purines because purines have two rings where as pyrimidines have only one ring.
Pyrimidines (cytosine, thymine, uracil) have a single-ring structure, while purines (adenine, guanine) have a double-ring structure. Purines always pair with pyrimidines in DNA and RNA bases. Additionally, purines are larger molecules compared to pyrimidines.
Purines and pyrimidines are nitrogen bases found in DNA and RNA .They are nitrogen containing heterocyclic compounds .Purines are large double ringed while pyrimidines are small single ringed .
Nucleic acids
Purines and pyrimidines are the building blocks of nucleic acids. The difference between purines and pyrimidines is in the number of carbon-rings present. Pyrimidines contain one carbon-ring while purines have two.
Watson thought of that as possible when he was under a misapprehension as to the structure of the nucleotides ( he thought enol when it was keto ). The backbone would be kinked and crooked, not smooth and seamless as it truly is.

Adenine and Guanine are purines, and Thymine and Cytosine are pyrimidines.
Pyrimidines (cytosine, thymine, uracil) have a single-ring structure, while purines (adenine, guanine) have a double-ring structure. Purines always pair with pyrimidines in DNA and RNA bases. Additionally, purines are larger molecules compared to pyrimidines.
Cytosine and thymine. one is a double ring sugar while the other is a single ring suagr. They are complemetarily paired with purines.
Purines bond to pyrimidines in nucleic acid DNA .
The two classes of nitrogen bases are purines and pyrimidines. Purines include adenine and guanine, which have a double-ring structure, while pyrimidines include cytosine, thymine, and uracil, which have a single-ring structure.
Purines and pyrimidines are nitrogen bases found in DNA and RNA .They are nitrogen containing heterocyclic compounds .Purines are large double ringed while pyrimidines are small single ringed .
Adenine and guanine, being purines ( double ringed ) always bond with thymine and cytosine, single ringed pyrimidines.
There are two purines (adenine and guanine) and two pyrimidines (cytosine and thymine) present in the DNA molecule.
