Web12 sep. 2024 · Answer and Explanation: The nitrogenous bases with two ringed structures are the purines and thus are bigger than the pyrimidines. The purines comprise of nine-membered structure with four typical nitrogen atoms. In contrast, pyrimidines have a single ring structure and are smaller than purines. Web25 feb. 2024 · NMN, NR and the nicotinamide moiety of NAD + were observed making multiple hydrogen bonding interactions at sites 1 and 2. At site 1 the pyridyl ring is coplanar with the G33:C46 base pair, and stacked between the C5:G34-A45 triple, and the G6:C32:A47:U7 quadruple interaction, making a probable cation-π interaction with G6.
