Summary Introduction
Introduction:
Bacterial transformation is the process of genetic alteration of a bacterial cell resulting from the direct uptake, incorporation, as well as expression of exogenous genetic material (exogenous DNA [deoxyribonucleic acid]) from its surroundings via the cell membrane.

A culture of Salmonella bacteria is exposed to the same concentrations (200 mg/L) of an antibiotic for four days. The table shows the number of isolated resistant bacteria over a four-day period. Which of the following statements best explains these results? A - The bacteria were not affected by the antibiotic. B - After being exposed to the antibiotic, the bacteria altered their DNA. C - A new species of bacteria emerged after the antibiotics were introduced.
