A topoisomerase unwinds the DNA molecule from complex structures of the interphase chromatin. A helicase separates the two antipolar strands of the double helix. Protein groups stabilize the single strands and prevent immediate complementary mating. A DNA polymerase (pole δ) has been continuously adding 3' → 5' to the lead strand to the semi-coservative, semi-new double helix since its start at Origin (Fig. taken from Wikipedia).
