Antibiotic Resistance

Key terms:

Mutation-  random unpredictable change in the DNA

Natural Selection- environment of bacteria selects bacteria able to survive

Too many antibiotics lead to antibiotic resistance

When a pathogen becomes unable to be removed, it has gained resistance to the antibiotic caused by mutation in the DNA

1.  A bacterium has developed resistance to the antibiotic 

2. Bacterium can reproduce to create more anti- biotics 

3. New antibiotic resistant bacteria are produced by natural selection 

Scientists have to develop a new antibiotic to kill the bacteria
