Respuesta :
Pyrimidines have one ring and two nitrogens, whereas purines have two rings and each has two nitrogens.
What exactly are pyrimidines and purines?
Adenine and guanine are nitrogen bases with two carbons, whereas cytosine and thymine are nitrogen bases with one carbon.
How can purines and pyrimidines be distinguished from one another?
The two purines are adenine and guanine, and the three pyrimidines are cytosine, thymine, and uracil. Purines and pyrimidines differ primarily in that purines have a six-membered nitrogen-containing ring fused to an imidazole ring while pyrimidines only have one such ring.
Where are pyrimidines and purines located?
The two distinct types of nitrogenous bases that make up nucleotide bases in DNA and RNA are purines and pyrimidines. Adenine and guanine, which each have two carbons in their nitrogen ring, are purines, while thymine and cytosine are pyrimidines.
