Sugar-phosphate-base

Vedclass · Answer

(D) Nucleic acids are polymers of nucleotides. Each nucleotide consists of a nitrogenous base,a pentose sugar,and a phosphate group. In the structure of a nucleic acid,the backbone is formed by the alternating sequence of sugar and phosphate groups,while the nitrogenous bases are attached to the sugar units. Therefore,the repeating unit in the backbone is sugar-phosphate,with the base attached to the sugar. Among the given options,the sequence of components in a nucleotide unit is often represented as sugar-phosphate-base (where the base is attached to the sugar). However,if referring to the backbone chain specifically,it is sugar-phosphate. Given the options provided,$D$ is the most appropriate representation of the structural arrangement.
