Question

multiple choice question

in bacterial conjugation, which term refers to a recipient cell that does not have a fertility plasmid?

hfr
(f^-)
(f^+)

Explanation:

Identify the definitions of conjugation terms

• \(F^+\) cells contain the F plasmid (fertility factor) and act as donors.
• \(F^-\) cells lack the F plasmid and act as recipients.
• Hfr (high frequency of recombination) cells have the F plasmid integrated into their chromosome.

Match the question criteria

• The question asks for a recipient cell that does not have a fertility plasmid.
• This corresponds to the \(F^-\) cell.

Answer:

• Hfr
• \(F^-\) (Correct answer)
• F+
