Determine whether or not each structure is a nucleotide. For each nucleotide, identify the base as A, T, C, or G.
Solution 63E: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 (a) and (c) contains a pentose sugar, anitrogenous base and a phosphate group. Hence, option (a) and (c)are nucleotides.Option (b) is adenine(nitrogenous base) whereas option(d) is methionine(amino acid).\na.\nc.In the option (a) base is adenine(A) and in option (c) base is thymine(T).
