In the mechanics of conjugation,exclusive of gene transfer,Hfr and F⁺ strains behave the same.

Question

Quizplus · Accepted Answer

Hfr and F⁺ strains both have the F factor integrated into their chromosome, which allows them to transfer genetic material to other bacteria. However, Hfr strains have the F factor integrated at a specific location on the chromosome, while F⁺ strains have the F factor integrated at a random location. This difference in integration location affects the way that the two strains transfer genetic material. Hfr strains transfer genetic material in a unidirectional manner, starting from the F factor integration site and moving towards the terminus of the chromosome. F⁺ strains, on the other hand, transfer genetic material in a bidirectional manner, starting from the F factor integration site and moving towards both the terminus and the origin of the chromosome.
