This theme of physiological irreversibility of hydrolysis is used consistently in metabolic pathways, since many biological processes are driven by the cleavage of anhydrous pyrophosphate bonds. DNA replication is semi-conservative, one strand serves as the template for the second strand. Furthermore, DNA replication only occurs at a specific step in the cell cycle. The following table describes the cell cycle for a hypothetical cell with a 24 hr cycle.

The formation of a phosphodiester bond releases pyrophosphate; the hydrolysis of pyrophosphate drives the reaction forward.

it is exothermic, releasing energy, thus driving the reaction forward. The energy released from PPi can be used to bind another nucleotide to the strand. PPi can be hydrolyzed further into 2Pi in order to release even more energy.
