What Is The Difference Between The Purines And The Pyrimidines

What is the difference between purine and pyrimidine.

Purine has a pyrimidine ring and an imidazole ring. Both are used for the production of dna and rna. They are opposite poles and same number of hydrogren connection bonds a pur t pyr c pur g. The main difference between purines and pyrimidines is that purines contain a six membered nitrogen containing ring fused to an imidazole ring whereas pyrimidines contain only a six membered nitrogen containing ring.

The reason behind this difference in melting and boiling points is that the molecules of purines are complex and heavy. Amino acids given below in a tabular column are the differences between purines and pyrimidines. In dna the purine adenine bonds to the pyrimidine thymine and the purine guanine bonds to the pyrimidine cytosine. Why do you think purines bond with pyrimidines in the dna ladder.

Purines ag pu 2 rings pyrimidines ct py 1 ring. Pyrimidine has one ring and purine has two rings. Why do you think purines bond with pyrimidines in the dna ladder. Purines adenine and guanine are two carbon nitrogen ring bases while pyrimidines cytosine and thymine are one carbon nitrogen ring bases.

Purines are quite common in meat products such as liver and kidney. What is the difference between the purines and the pyrimidines. Purines are larger than pyrimidines because they have a two ring structure while pyrimidines only have a single ring. You should now feel confident in your ability to identify and differentiate between purines and pyrimidines as well as in your knowledge of what role they play in dna structure.

Pyrimidines are the heterocyclic aromatic organic compounds that have a single carbon nitrogen ring attached with two nitrogen atoms. Purines participate in greater number of molecular reactions in comparison to pyrimidines. More sources and references. While purines and pyrimidines include molecules that are active on their own as in drugs and vitamins they also form hydrogen bonds between each other to link the two strands of the dna double helix and to form complementary molecules between dna and rna.

The two carbon nitrogen ring bases adenine and guanine are purines while the one carbon nitrogen ring bases thymine and cytosine are pyrimidines. Purines are the heterocyclic aromatic organic compounds that possess two carbon nitrogen rings attached with four nitrogen atoms.
