1.  In  the  F^+, the two strands of the double helix of the Fertility
   (F) factor (a plasmid) separate.
   2. One of the two strands moves into the recipient (F^-) cell.
   3. The other strand remains in the donor cell.
   4.  Both  strands  are  replicated,  with  clockwise  rotation  of the
   circles.
   5.  Both  the  donor  and  the  recipient  cells  are  now  F^+  after
   conjugation.
