Plasmid vectors,erial chromosome. They can also mobilise DNA to which they are not covalently joined and this includes co-existing non-conjugative plasmids. In this Chapter I will trace the modification of several non-conjugative plasmid vectors to give more effective cloning vehicles which can no longer be effectively mobilised during conjugation.作者: Indelible 時(shí)間: 2025-3-22 03:47 作者: 折磨 時(shí)間: 2025-3-22 07:33
