In a Conjugation Experiment Not All of the Cells Receiving

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
