Which of the following statements about Hfr cells and bacterial conjugation is false? An Hfr cell becomes an F- cell if its integrated F plasmid is excised. If excision of the F plasmid from an Hfr cell includes some bacterial genes, a partial diploid can result. Cells with integrated F' plasmid have two copies of some genes. An F' plasmid contains some bacterial genes. The genes that are transferred from an Hfr cell into a recipient cell during conjugation replace the equivalent genes in the recipient cell.
