How do Bacteria become Resistant?

ANTIBIOTIC RESISTANCE: - Bacteria can evolve quickly because they reproduce at a fast rate. Mutations of bacteria produce new strains - Some bacteria might become resistant to certain antibiotics, such as penicillin, (can't be destroyed by the antibiotic), bacteria evolution is an example of natural selection Development of resistance: 1) random mutations occur in the genes of individual bacterial cells 2) some mutations protect the bacterial cell from the effects of the antibiotic 3) bacteria without the mutation die or cannot reproduce when the antibiotic is present 4) resistant bacteria can reproduce with less competition from normal bacterial strains
