WebTwo prominent mechanisms have been proposed for RNA and protein enzyme catalyzed cleavage of phosphodiester bonds in RNA: (a) intramolecular nucleophilic attack by the 2'-hydroxyl group adjacent to the reactive phosphate; and (b) intermolecular nucleophilic attack by hydroxide, or other oxyanion. WebPhosphodiester bond is a type of chemical bond, that helps to join two successive sugar molecules in a polynucleotide but peptide bond is a type of chemical covalent bond that is formed between the reaction of two successive amino acid. Similarities and differences between these two bonds are pointed out in this article.
