1)How do bacteria reproduce? Why are bacteria great organisms to use in biological experiments?

2.            What are the three ways genetic transfer occurs in bacteria? Could this lead to genetic variation? What else would lead to genetic variability? Does information flow in both directions or only one direction?

3.            What is a plasmid?

4.            What is a bacterial colony? What is an auxotroph? What is a prototroph?
