Question

What is the difference between purine and pyrimidine?

Answer 1

One of them which is also referred to as (adenine and guanine) are two-carbon nitrogen ring bases while the other one is known as (cytosine and thymine) are one -carbon-nitrogen ring bases.

Complete step-by-step answer:

Purines	Pyrimidine
Purine refers to a heterocyclic aromatic organic compound that is made of a pyrimidine ring that is fused with an imidazole ring.	Pyrimidine is referred to as a heterocyclic aromatic organic compound that is composed of carbon and hydrogen.
It consists of adenine and guanine both as nucleobases.	It consists of Cytosine, thymine, uracil as nucleobases.
Purines also consist of two hydrogen-carbon rings as well as four nitrogen atoms.	Pyrimidine comprises one hydrogen-carbon ring and two nitrogen atoms also.
Catabolism results in uric acid’s production.	Catabolism produces carbon dioxide, beta-amino acids as well as ammonia, both.
Purine’s melting point is ${214^{}}$ degrees Celsius.	Pyrimidine’s melting point is $20 - 22$ degrees Celsius.

Note: Purine & Pyrimidine, both are organic compounds taking part during the synthesis of DNA & RNA. They are nitrogenous bases that make up the two different nucleotides in DNA as well as RNA.
