- In a DNA oligonucleotide, two nucleosides are linked together with a: Phosphodiester bond Phosphatic bond Phosphoester bond Glycosidic bondThe linkage between individual nucleotides in DNA is known as a phosphodiester bond because— two esters are connected by a single covalent bond whose formation is catalyzed by a phosphate. a double bond is formed in the process of esterification of a phosphate group. a nucleoside diphosphate is involved and each phosphate forms one ester. a single phosphate is esterified to two deoxyribose units. two bonds are phosphorylated into one single bondHow many amino acids are present on the helix to the right?
