Why do we need a plasmid to transform a bacteria? What are the essential components of a plasmid and explain their functions. What is the difference between a Plasmid and a Vector?

How can plasmids benefit humans?

What is the process called when bacteria exchange small pieces of DNA called plasmids or vectors that contain antibiotic resistant genes.

What would happen to a bacteria that lost a plasmid for antibiotic resistance?  Would it still be able to grow in normal growth conditions?  Explain.

What is SDS and what part does it play in the alkaline lysis method of preparing plasmid DNA from a culture of bacteria?

What is it called when F+ cell donates a dna plasmid to F-?

In a hypothetical situation, the gene for tetracycline resistance is located on a plasmid within a particular bacterium. This bacterium readily forms a pilus and donates one strand of the plasmid to another bacterium. What do you know about the bacterium with the tetracycline resistance? O It cannot receive a plasmid from another bacterium. O It must have the F factor gene because it can perform conjugation. O If it donates the plasmid, it will lose its own tetracycline resistance. O It has the Hfr gene and it can participate in transformation.

How are we to know which of the bacteria have taken up the plasmid?
