Alcanivorax is a naturally occurring oil-degrading marine bacterium that can quickly become the predominant microbe in oil-contaminated open oceans and coastal waters. To identify the genes important for the oil-degrading ability, you could attempt the following:

1) You might begin by identifying mutant Alcanivorax cells with a specific phenotype. For what mutant phenotype would you screen? Answer by completing the following statement: The mutant cells would not be able to...

unanswered

2) For your second step you might make a bacterial DNA library. What type of bacterial cells would you use as a source for the genomic DNA library?

unanswered

3) Finally, you could transform the mutant cells identified with the bacterial DNA library as given above. How would you identify cells that have a recombinant plasmid carrying a gene involved in oil degradation?

unanswered
