In the polynucleotide chain of \(DNA\), a nitrogenous base is linked to the \(-OH\) of
- A \(1^{\prime} C\) pentose sugar
- B \(2^{\prime} C\) pentose sugar
- C \(3^{\prime} C\) pentose sugar
- D \(5^{\prime} C\) pentose sugar
Answer & Solution
Correct Answer
(A) \(1^{\prime} C\) pentose sugar
Step-by-step Solution
Detailed explanation
The correct answer is option (1) as in the polynucleotide chain of DNA, a nitrogenous base is linked to the \(- OH\) of \(1^{\prime} C\) of pentose sugar.
Option (3) and (4) are incorrect as phosphodiester bond is present between \(3^{\prime}\) carbon of sugar of one nucleotide to the \(5^{\prime}\) carbon of the sugar of the succeeding nucleotide.
Option (3) and (4) are incorrect as phosphodiester bond is present between \(3^{\prime}\) carbon of sugar of one nucleotide to the \(5^{\prime}\) carbon of the sugar of the succeeding nucleotide.
