Pyrimidine is a heterocyclic aromatic organic compound similar to benzene and pyridine, containing two nitrogen atoms at positions 1 and 3 of the six-member ring. In the first class, the pyrimidine motif, the third strand binds parallel to the purine strand of the duplex, forming T.A*T and C.G*C+ triplets ( 2, 3, 15, 16). Ultimately, aside from the fact that purines have two-carbon nitrogen rings and that pyrimidines only have one-carbon rings, their main difference is that in a purine catabolism, the main breakdown ends in uric acid, while in a pyrimidine catabolism, the main breakdown ends … Draw a short segment of a single polynucleotide strand, including at least three nucleotides. The main difference between transition and transversion is that transition is the conversion of purine to another purine base or pyrimidine to another pyrimidine base whereas transversion is the conversion of a purine into a pyrimidine or vice versa. For these reasons, their determination has been the object of much attention during the last 25 years, and a number of methods have been proposed. NCERT.
