Metabolize

... help with these two homework questions. I have no idea where/how to start to figure these out. You have isolated several yeast mutants unable to metabolize galactose. All of the mutants fail to transcribe the GAL2 gene, which encodes the enzyme for the first step in metabolizing galactose. For ...

I should think that the frame shift mutation that resulted in bacteria that could metabolize the byproducts of nylon manufacture would be an example of this. As would be the several mutations that seem to confer immunity to HIV. Or ...

This would have the advantage of telling you exactly how fast you metabolize caffeine (within the margin of error - which, of course, you can reduce by doing replicates), including any effects on caffeine metabolism ...
