Draw a diagram/figure to explain the conjugation process (e.g. use PowerPoint or draw one by hand and include a photo of it). You should include in the diagram the F- recipient, Hfr Donor and the transconjugant/recombinant recipient. Make sure to include the genes encoding for Leucine, Threonine, Thiamine and Streptomycin resistance in your diagram. How does an Hfr strain of coli transfers chromosomal DNA to an F- strain? What determines how much of the chromosomal DNA is transferred?

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
