Question

Part D How do we know that bacteriophages recombine genetic matenal through transduction and that cell-to-celll contact is not essential for transduction to occur? O Bacterial contact can be eliminated with a U-tube Bacterial contact can be eliminated with a filter Bacterial contact can be eliminated with both a U-tube and a filter This is a hypothesis, no evidence is provided yet O Submit Request Answer Part E How do we know that intergenic exchange occurs in bacteriophages? O It was demonstrated by using a Davis U-tube without a filter It was demonstrated by using a Davis U-tube and a titer O It was demonstrated by mixed infections that yielded recombinants O It was demonstrated by a single infection that yielded recombinants

Explanation / Answer

Part D: answer is option c bacterial transduction cannot take place without physical contact is evident from Davis experiment in 1950. Which proves transduction cannot take place using a Davis u tube and filter. As through the filter matter can pass but not two different strains of bacteria.

Part E demonstrated by single infection yeilding recominants
