Abstract
Separation of HfrC-F- mating pairs of Escherichia coli by a filter 6 microns thick with straight-through pores 0.01 to 0.1 micron in diameter did not prevent DNA transfer. We conclude that the F pilus alone is capable of acting as a stable conduit for cell-to-cell DNA transfer.
摘要
用孔径为0.01至0.1微米、厚度为6微米且孔为直通式的滤膜分离大肠杆菌的HfrC - F - 交配配对，并不妨碍DNA转移。我们得出结论，单独的F菌毛就能够作为细胞间DNA转移的稳定通道。
