Biosynthesis and activity of DNA polymerase throughout the mitotic cycle of Physarum polycephalum

Abstract
Measurements of DNA polymerase protein levels and polymerase activity through the naturally synchronous mitotic cycle of Physarum polycephalum show that active DNA polymerase‐α is synthesized throughout the G2 phase, in step with the profile of general protein biosynthesis. Three main components of P. polycephalum DNA polymerase of 200, 112 and 70 kDa were found to be immunologically related.
