E. coli is a bacterium that is routinely used in cloning experiments and can be grown on artificially synthesized media in the laboratory. One of the strains of this bacterium, XL-1 Blue, is naturally resistant to the antibiotic, tetracycline. A genetic transformation experiment was performed to introduce a plasmid that encodes an ampicillin resistance gene into this strain. Following transformation, an equal number

Options

  1. AThe transformation efficiency of cells is lower than their viability.
  2. BUntransformed cells also grew on growth medium "A".
  3. CTetracycline was inhibitory to the growth of bacterial cells.
  4. DAmpicillin did not allow transformed cells to grow on growth medium "B".

Correct answer

B. Untransformed cells also grew on growth medium "A".
