What are the phenotypic and genotypic differences between ce

What are the phenotypic and genotypic differences between cells that are Hfr and F+?

To answer this question, you may need to describe experiments that you could do if you had two cells on plates. One people Hfr and the other being F+, but you were not told which was which.

Solution

An F+ cell will accommodate a round plasmid distinct from the chromosome. the Hfr cell has the f factor non-segregated into its chromosome. in F\' strains the f factor survive as a unrelated round plasmid but the plasmid transfer bacterial genes that were initially role of the bacterial chromosome. The F- strain does not accommodate the f factor and can accept DNA from cells that accommodate the F factor. (F+, Hfr, and F\' )
