Ka whakaputa i tētahi putanga matatini ake o tēnei rerenga kōrero I muri i te whakaekenga o te aho, ka whakawhānuihia e te DNA polymerase te pito o te aho 3'whakaekenga mā te waihanga i te DNA hou.
Ko te tikanga, ko tētahi putanga matatini ake o te rerenga kōrero, "I muri i te whakaekenga o te aho, ka whakawhānuihia e te DNA polymerase te aho 3' whakaekenga, ka huri i te D-huringa ki te hanganga anga ripeka e mōhiotia ana ko te hononga Holliday. "
