Bacterial conjugation
Drag each phrase into the appropriate bin depending on whether it applies to an F+ cell, an Hfr cell, or an F- cell. (Remember that we are only considering conjugation involving the F factor here, and not other mechanisms for transferring genetic material.)
F+ cell:
1) carries the F factor in a plasmidmay
2) may donate a plasmid to another cell

Hfr cell:
1) carries the F factor in its circular chromosome
2) may donate genes from its chromosome to another cell

F- cell:
1) may become F+ after conjugation with an F+ cell
2) may become recombinant after conjugation with an Hfr cell
3) may receive genetic material, but cannot donate genetic material

Answer:

Yes, these are correct.

Explanation:

  • Bacterial conjugation is the bacterial counterpart of sexual reproduction. Also known as horizontal gene transfer, it involves the transfer of genetic material from one F+ or Hfr bacterium to another F+ or F- bacterium.
  • The F or fertility factor is a crucial component of the bacterial plasmid and it accounts for the development of sex pili which are important for conjugation. An F+ cells contains the F-factor incorporated into its plasmid, whereas an F- cell lacks the F-factor and therefore cannot participate in conjugation.
  • Conjugation between an F+ and F- cell can result in the transfer of the F-factor to the F- bacterium.
  • An Hfr bacterium contains F-factor incorporated into its circular genome.
