Two nucleotides are joined together by a linkage known as :

Options

APhosphodiester linkage
BGlycosidic linkage
CDisulphide linkage
DPeptide linkage

Correct answer

A. Phosphodiester linkage

Step-by-step solution

The bond joining two successive nucleotides in the same strand of DNA is called the phosphodiester bond. the phosphodiester bond is the linkage between the ${3}^{'}$ carbon atom of one sugar molecule and the ${5}^{'}$ carbon atom of another, deoxyribose in DNA and ribose in RNA.
