One outcome is that one of two semi-conservatively replicated F plasmids remains in the donor cell and another is now in the recipient cell. In this case, the recipient cell becomes a new F+ donor cell! 2. The other outcome is integration of the F plasmid into recipient cell chromosomal DNA. cancelled hunting trips for sale
