QUESTION 5

Which of the following treatments, when applied during the phage cross, would be expected to decrease the frequency with which the half-and-half phage appear among the progeny? Briefly explain your choices. (If multiple choices are possible, list and explain all):

            A) Block transcription                                  

            B) Block translation                                      

            C) Block DNA replication                            

            D) Block recombination

            E) Block DNA mismatch repair

            F) Block phage int function

Explanation / Answer

Among the options listed above, only option (D) Block recombination can decrease the frequency with which only half and half phage appear in the progeny.

Blocking recombination of the host prevents the two parental phage DNA from recombining and producting recombinant phage.

Options A,B,C will all block the DNA of the phage from being able to propagate in one way or another and this will lead to NO phage progeny production.
