A)occurs at the rate of about once in every 109 cell divisions.
B)may occur as a result of exposure to radiation.
C)may result in the organism acquiring better characteristics.
D)may result the organism becoming resistant to antibiotics.
E)all of the above.

Accepted Answer

All of the statements are true. Mutations can occur spontaneously or as a result of exposure to various mutagens, including radiation. Some mutations may confer an advantageous trait to the organism, such as antibiotic resistance, while others may be neutral or harmful. The rate of mutation varies among different species and environments, but it is generally low, occurring at a frequency of about once in every 109 cell divisions in bacteria.
