Which bond is established when a phosphate group is linked to OH of 5' C of a nucleoside?

When a phosphate group is linked to OH of 5' C of a nucleoside through phosphoester linkage, a corresponding nucleotide is formed.
A nitrogenous base is linked to the OH of 1' C pentose sugar through a N-glycosidic linkage to form a nucleoside. 
Two nucleotides are linked through 3'-5' phosphodiester linkage to form a dinucleotide.
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water.
