3. This antibiotic kills the staphlococcus aureus. 
4. The type of staphlococcus aureus which can be killed by the antibiotic are known as susceptible form (mssa)
5. When a random mutation occurs within the genome of the staphlococcus aureus, the methecilline fails to kill it. This form is known as the resistant form of staphlococcus aureus. (mrsa)
