  1. can be used to eliminate the function of any gene in the genome.

  2. can be used to introduce entire genomes into bacterial cells.
  3. allow the expression of many or even all of the genes in the genome to be compared at once.
  4. allow physical maps of the genome to be assembled in a very short time.

A researcher would like to map the location of galE and trpA genes in a new species of bacterium that appears to be closely related to E. coli. He decides to use cotransduction, and generatesnappropriate donor and recipient strains. He is disappointed when cotransduction is not seen in his experiement. What is the most reasonable explanation for this situation?
