inheritance (antibiotic resistance)

Question 1

name the 4 stages of antibiotic resistance

Answer 1

1. mutation
2. death
3. reproduction
4. result

Question 2

describe the mutation stage of antibiotic resistance

Answer 2

1. a random mutation occurs in the DNA of individual bacterial cells. the mutation protects the bacterial cell from the effects of the antibiotic- it becomes antibiotic resistant

Question 3

describe the death stage of antibiotic resistance

Answer 3

2. bacteria without the mutation die when an antibiotic is present

Question 4

describe the reproduction stage of antibiotic resistance

Answer 4

3. antibiotic resistant bacteria survive and can reproduce with less competition from non-resistant bacterial strains. the genes for antibiotic resistance are passed onto more offspring

Question 5

describe the result stage of antibiotic resistance

Answer 5

4. over time the whole population becomes antibiotic resistant because the antibiotic resistant bacteria are best suited to their environment.
