Vedclass · Answer

(D) The backbone of a polynucleotide chain (like $DNA$ or $RNA$) is formed by the sugar-phosphate chain. $1$. Each nucleotide consists of a nitrogenous base,a pentose sugar,and a phosphate group. $2$. The sugar of one nucleotide is linked to the phosphate group of the adjacent nucleotide through a phosphodiester bond. $3$. This alternating sequence of sugar and phosphate molecules creates the structural backbone of the polynucleotide strand,while the nitrogenous bases project inward from this backbone.
