The transfer of genetic material from one bacterium to another through the mediation of a viral vector is termed as
1. transduction
2. conjugation
3. transformation
4. translation
Significance of 'heat shock' method in bacterial transformation is to facilitate:
1. | Binding of DNA to the cell wall |
2. | Uptake of DNA through membrane transport proteins |
3. | Uptake of DNA through transient pores in the bacterial cell wall |
4. | Expression of antibiotic resistance gene |
