Two nucleotides are joined together by a linkage known as:
Disulphide linkage
Glycosidic linkage
Phosphodiester linkage
Peptide linkage
The Correct Option is C
Solution and Explanation
The bond connecting two nucleotides in a nucleic acid chain is called a phosphodiester linkage, as it involves a phosphate group bonding with two sugar molecules, forming an ester bond on both sides.

Concepts Used:
Nucleic acids
Nucleic acids are explained as long-chain polymeric molecules, where the monomer (the repeating unit) is referred to as the nucleotides. Thus many times nucleic acids are referred to as polynucleotides. The two main kinds of nucleic acids are-
Deoxyribonucleic Acid (DNA)
Chemically, DNA is a composition of a pentose sugar, phosphoric acid, and some cyclic bases that have nitrogen in them. DNA has β-D-2-deoxyribose in it, in the form of the sugar moiety.
Ribonucleic Acid (RNA)
The RNA molecule is a composition of phosphoric acid, a pentose sugar, and some cyclic bases containing nitrogen. The sugar moiety inside RNA molecules is β-D-ribose.
