Questions and Answers

Which of the following is required for conjugation to occur in bacteria?

  • Transfer of DNA
  • Presence of a fertility factor on a plasmid
  • Production of a sex or conjugation pilus
  • Close contact between two cells (correct)

    • What is the role of the fertility factor (F factor) in conjugation?

  • It carries the genes for conjugative transfer (correct)
  • It facilitates the transfer of DNA
  • It binds to the recipient F− cell
  • It produces a sex or conjugation pilus

    • What happens when the F factor is integrated into the bacterial chromosome instead of a plasmid?

  • The fertility factor is lost
  • The conjugation pilus is not produced
  • There is a higher frequency of transfer of adjacent bacterial chromosomal genes (correct)
  • The bacteria become high-frequency recombination strains
