What does bacterial growth on a plate containing a particular trait (such as antibiotic resistance) after a bacterial conjugation experiment indicate? A. The bacterial colonies have acquired the trait from the F- strain (recipient). B. The bacterial colonies have resisted the trait and not undergone conjugation. C. The bacterial colonies have undergone mutation and developed the trait on their own. D. The bacterial colonies growing on the plate have likely undergone conjugation and acquired the desired trait from the F+ strain (donor).

What must occur for bacterial conjugation to take place? A. The cells must transfer RNA. B. One of the cells must be E. coli. C. The cells must come into contact with each other. D. Each cell must contain a plasmid.

True or False: Can two different species of bacteria conduct bacterial conjugation? Responses True, as long as they have identical chromosomal DNA. True, as long as they have identical chromosomal DNA. True, as long as there is a plasmid to be transferred between them any bacteria can do it. True, as long as there is a plasmid to be transferred between them any bacteria can do it. False, they have different genus. False, they have different genus. False, the pilus would not form a hollow bridge since they are different species

True or False: For conjugation to occur, bacterial cells must physically contact each other. A True B False
