Add one of four dNTP’s, DNA polymerase incorporates dNTP’s (if it is complementary) releasing PPi. ATP sulfurylase converts PPi and APS to ATP. Luciferase converts luciferin and ATP to oxyluciferin which generates light read by a camera. Apyrase degrades dNTP’s and ATP, when complete next dNTP is added. As process continues, the correct DNA sequence is built up and displayed.Pyrosequencing
