The $3^{\prime}-5^{\prime}$ phosphodiester linkages inside a polynucleotide chain serve to join
The $3^{\prime}-5^{\prime}$ phosphodiester linkages inside a polynucleotide chain serve to join
one DNA strand with the other DNA strand
one nucleoside with another nucleoside
one nucleotide with another nucleotide
one nitrogenous base with pentose sugar
Solution
In a polynucleotide chain, $3^{\prime}-5^{\prime}$ phospho diester bond is formed between carbon 3 of one nucleotide and carbon 5 of the other nucleotide, ie, it serves to join one nucleotide with another nucleotide in a polynucleotide chain.
