Vedclass · Answer

(B) $DNA$ molecule consists of two antiparallel strands. In a single strand of $DNA$ with $n$ nucleotides,there are $(n-1)$ phosphodiester bonds. For $10$ base pairs,each strand contains $10$ nucleotides. Number of phosphodiester bonds in one strand = $10 - 1 = 9$. Since there are two strands in a $DNA$ molecule,the total number of phosphodiester bonds = $9 + 9 = 18$.
