Question

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.

Answer 1

Answer:

An Hfr cell becomes an F- cell if its integrated F plasmid is excised.

Explanation:

In a typical bacteria chromosome movement by the cells of the high-frequency recombination, there is the movement of a segment of the genome of the specific bacterial. It is also unlikely for the complete movement of the conjugate. Therefore, based on all the available options in the problem above, the false statement is the first option.
