When it comes to the conjugation of an Hfr bacterium and an F- bacterium, which of the following statements is not true?

The DNA of the main chromosome is transferred to a recipient cell during an Hfr X F- conjugation.

During conjugation, the Hfr and F- bacteria establish a physical connection.

Genes from the Hfr bacterium that is close to the leading sides of the F origin of transfer are more likely to be transferred to the F- bacteria than genes from the F- bacteria that are further away.

As the Hfr chromosome replicates, the free 3' end moves through the transfer pore that connects the two bacteria.
