-F plasmids. //oriT// (erroneously labeled as OriT in the figure) is the origin of transfer (related to how F is transmnitted from one host to another) for the F plasmid, and the //tra// genes (erroneously labeled as Tra in the figure) are required for forming the pilus needed for transfer of the F plasmid from one cell to another (see Fig. {{ref>Fig2}}). F plasmids are about 10<sup>5</sup> bp long; for comparison, the size of the circular //E. coli// chromosome is 5x10<sup>6</sup> bp, or over 10-fold longer.+F plasmids. //oriT// (erroneously labeled as OriT in the figure) is the origin of transfer (related to how F is transmitted from one host to another) for the F plasmid, and the //tra// genes (erroneously labeled as Tra in the figure) are required for forming the pilus needed for transfer of the F plasmid from one cell to another (see Fig. {{ref>Fig2}}).

-Homologous recombination can sometimes occur at a different position to give excise an F plasmid that carries a part of the //E. coli// chromosome. In the example in Fig. {{ref>Fig6}}, this is the BC segment of the //E. coli// chromosome. This form of F is called an F' (pronounced “F prime”).+Homologous recombination can sometimes occur at a different position to excise an F plasmid that carries a part of the //E. coli// chromosome.
