What are the 3 ways bacteria can share genetic material? (Transduction, Transformation, and Conjugation)
Can you explain each of the 3 ways?
How do we know natural selection has acted on antibiotic resistance in bacteria?
1. Heredity - bacteria inherit the plasmid where the genes for resistance are found
2. Variability - resistance vs. non-resistance
3.Selective Pressure - Antibiotic
4. Differential Survival and Reproduction - In the presence of antibiotics (In the environment), if the bacteria has a gene for resistance it will survive and reproduce.
