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.
