State the dual role of deoxyribonucleoside triphosphates during DNA replication



Any mistake during replication would result into mutations.Furthermore, energetically replication is a very expensive process. Deoxyribo nucleoside triphosphates serve dual purposes. In addition to acting as substrates, they provide energy for polymerization reaction. The two terminal phosphates in a deoxynucleoside triphosphate are high-energy phosphates, the same as in the case of ATP.
