Vedclass · Answer

(A) Nucleic acids ($DNA$ and $RNA$) are polymers of nucleotides. $A$ nucleotide consists of a nitrogenous base,a pentose sugar,and a phosphate group. The phosphate group is derived from phosphoric acid $(H_3PO_4)$. In the structure of a nucleotide,the phosphoric acid is incorporated as a phosphate group $(PO_4^{3-})$. The chemical structure of phosphoric acid $(H_3PO_4)$ consists of a central phosphorus atom double-bonded to one oxygen atom and single-bonded to three hydroxyl $(-OH)$ groups. Option $A$ correctly represents the structure of phosphoric acid $(H_3PO_4)$ as it exists in its standard form before forming ester bonds in the nucleic acid backbone.
