Fig. 1: Comparison of PCR and SHARP.

a PCR alternates the temperature between high (≈98 °C) to melt the DNA duplex and low (45–65 °C) to replicate the complementary strand by a DNA polymerase. b SHARP uses PcrA M6 helicase and SSB to open the duplex and enable primer binding, followed by Bst-LF polymerase to replicate the strand. SHARP occurs at a constant temperature. Created with BioRender.com.
