If we consider the Lewis structures shown below, and count the lone pairs on N atoms which are pointing perpendicular to the planes of the rings as contributing to the cyclic array of 2p electrons, we see that both thymine and imidazole are aromatic. The Fluid Mosaic Model of the Cell Membrane | What Is the Fluid Mosaic Model? Due to these three hydrogen bonds, the cytosine-guanine base pair has an overall higher boiling point and greater bond strength than the adenine-thymine base pair. Cytosine. In fact, sometimes it accidentally loses a few atoms and becomes uracil, one of the bases in RNA. A purine, on the other hand, has two rings of carbon. As a nitrogenous base, cytosine is full of nitrogen atoms (it has three). Thymine is not found in RNA. It molecule forms a planar shape and is in a DNA double helix. 1) RNA is single stranded molecule, while DNA is double stranded. Cytosine (C) is one of the four nucleotide bases in DNA, with the other three being adenine (A), guanine (G) and thymine (T). In RNA, thymine is replaced by the nucleobase uracil.Thymine was first isolated in 1893 by Albrecht Kossel and Albert Neumann . The nucleotide of cytosine in DNA is deoxycytidylate which consists of a cytosine, ribose and phosphate. It is a pyrimidine derivative which has one heterocyclic aromatic carbon ring structure. For example, uracil glycosylase is extracted from DNA by cleaving the cytosine-turned-uracil. The main difference between cytosine and thymine is that cytosine is found in both DNA and RNA, complementary base pairing with guanine whereas thymine is only found in DNA, complementary base pairing with adenine. A series of condensation, oxidation, acid amine coupling and reductive amination reactions were performed to synthesize analogues of N-substituted 2-(pyridin-4-yl)-1H-imidazo[4,5-b] pyridine-7-carboxamide and (2-(pyridin-4-yl)-1H-imidazo[4,5-b] pyridin-7-yl) methanamine.Molecular structure confirmation of derivatives was acknowledged by modern analytical techniques like IR, 1 H NMR, 13 C NMR .
