C1. A recombinant microorganism is one that contains DNA that has been manipulated in vitro and then reintroduced back into the organism. Recombinant microorganisms have been used to synthesize human gene products (e.g., insulin), as biological control agents (e.g., Ice bacteria), and in bioremediation (e.g., oil-eating bacteria). C2. A. radiobacter synthesizes an antibiotic that kills A. tumefaciens. The genes, which are necessary for antibiotic biosynthesis and resistance, are plasmid encoded and can be transferred during interspecies matings. If A. tumefaciens received this plasmid during conjugation, it would be resistant to killing. Therefore, the conjugation- deficient strain prevents the occurrence of A. tumefaciens –resistant strains. C3. Bioremediation is the use of microorganisms to eliminate pollutants in the environment. Biotransformation is the conversion of a toxic compound into a nontoxic one. Biodegradation occurs when a toxic compound is broken down into a smaller, less toxic one. C4. A biological control agent is an organism that prevents the harmful effects of some other agent in the environment. Examples include Bacillus thuringiensis, a bacterium that synthesizes compounds that act as toxins to kill insects, Ice bacteria that inhibit the proliferation of Ice + bacteria, and the use of Agrobacterium radiobacter
