Question

nucleobase = one or two ring heterocyclic amine nucleoside = nucleobase + sugar nucleotide = nucleobase + sugar + some kind of phosphate = nucleoside + some kind of phosphate 1. Below are structures of ordinary nucleobases, nucleosides, and nucleotides. For each, state if it is based on purine or pyrimidine, then give the class (nucleobase, nucleoside, nucleotide) - e.g. purine nucleoside or pyrmidine nucleobase. (18 pts - 3 ea.) MA a) b) c) NH YUHA ol ON OH f) Ho por edhe ollo of oH

Answer 1

Solution is given below. Please go through it.
NE NE ZI Pwrine Skeletal Pyrimidine skeletal

NH2 2 @ Nuclcobase осо 6 0, OH OH Nucleotide It is contain pyrimidine = pyrimidine Nucleotide base Rheaphate sugar (b) o= NH Nucleobase "NH2 HO OH Nucleobase + suger =) Nucleoside It contains purine base Purine Nucleoside Sugar ( NH = Nucleobase → pyrimidine Nucleobase only Heterocylia base It contains one

(d) 05 NH Nucleobase o HO OH OH Sugar Nucleobase + sugar = Nucleoside It contains one Sysimidine base → Pyrimidine Nucleoside (e) ŅH2 Nuclcobase 3 11 .P. ol 0 OH OH =) Nucleotide It contains puine base =) Purine Nucleotide Phosphate sugar group OLNH = contains two Heterocyclic ring * Nucleobase Purune Nucleobase
