Which of the following statements about conjugation is false? After a F- cell has conjugated with an F+ cell, both cells would be F+. Both Hfr and F+ bacteria have the ability to produce a sex pilus. In F+ × F- conjugation, none of the bacterial chromosome is transferred; only the F factor is. A Hfr strain usually transfers the entire bacterial chromosome to the recipient cell. F' × F- conjugation can produce a partially diploid bacterial cell.

Explain the importance of the following features in conjugating donor bacteria: a. the origin of transfer b. the conjugation pilus c. homologous recombination d. the relaxosome e. relaxase f. T strand DNA g. pillin protein

The following recombinants are recovered when conjugation occurs between an a*d*g+ donor and an adg recipient. at d+ g+ = 84% a d g+ = 6% at d g+ = 10% a dt g+ = less than 1% What is the map distance between the a and d genes? 10 map units 74 map units less than 1 map unit 84 map units 6 map units
