The covalent bond that links nucleotides in the sugar-phosphate backbone is a phosphodiester bond.
Explanation:
Nucleotides are linked together by the formation of a phosphodiester bond which is formed between the 3' -OH group of one sugar molecule, and the 5' phosphate group on the adjacent sugar molecule. This results in a loss of a molecule of water, making this a condensation reaction, also called a dehydration synthesis.
