Determine whether or not each structure is a nucleotide. For each nucleotide, identify the base as A, T, C, or G.
Solution 64E:Nucleotides are the building blocks of nucleic acid. When a base attaches itself to C-1 of thepentose sugar, a nucleoside is formed. When nucleoside is linked to phosphoric acid at C-5 ofsugar moiety, we get a nucleotide. The general structure of a nucleotide is given below-There are total five bases that may be involved in the formation of a nucleotide.The structure of all the five bases are given below-In the above problem, out of all the options, only (c) contains a pentose sugar, a nitrogenousbase and a phosphate group. Hence, option (c) is a nucleotide.Option (a) is guanine(nitrogenous base), option(b) is glucose whereas option(d) is dipeptide(twoamino acids linked together by peptide bond).\n C.The base in option (c) is guanine(G).
