Adenine pairs with ThymineCytosine pairs with Guanine
No. The physical structure does not allow purines to pair with other purines. Purines can only be paired with Pyrimidines.
Purines because purines have two rings where as pyrimidines have only one ring.
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 .

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.
Purines because purines have two rings where as pyrimidines have only one ring.
Adenine and Guanine are purines, and Thymine and Cytosine are 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 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 .
Purines bond to pyrimidines in nucleic acid DNA .
Adenine is paired with thymine.Cytosine is paired with guanine.
Adenine and guanine, being purines ( double ringed ) always bond with thymine and cytosine, single ringed pyrimidines.
A purine has a double ring, while a pyrimidine has a single ring. Also purines are adenine and guanine, and the pyrimidines are thymine and cytosine.
