In a Conjugation Experiment Not All of the Cells Receiving

question 40

Multiple Choice

In a conjugation experiment not all of the cells receiving two genes will demonstrate an altered phenotype for both genes. What is the most likely explanation of this phenomenon?

• A) One gene is toxic to the cell
• B) Transferred genes must undergo recombination for genotypic conversion of the recipient cell and there is a possibility that only one gene will be recombined into the recipients chromosome
• C) The transferred DNA is rapidly degraded by the recipient cell and one gene can be degraded before it is recombined into the host chromosome
• D) It is not physically possible to recombine more than one gene into a single host genome per conjugation event
