Which one of the following is likely to occur in E. coli cells that are grown in skim milk? - e coli. cells grown on 15n medium are transferred
a) the trp operon is on bacteria, but not on porduce lactose using enzymes.
activated b) the trp repressor and the cells that lactose using enzymes.
c) the lac operon is a haven outside the cells and not the production of the enzyme lactose.

E Coli. Cells Grown On 15n Medium Are Transferred Which One Of The Following Is Likely To Occur In E. Coli Cells That Are Grown In Skim Milk?

As milk protein and lactose (also contains "milk sugar"), then no E. coli tryptophan, but would like to lactose metabolism. Therefore, the responses are scanned to see and those who are lactose operon (bacterial enzymes) metabolism of lactose and see what the responses of the trp operon is turned off and produce (the bacterium does not need the synthesis of tryptophan).
I have no exact answer, but I have a website for the U of milk refer only to find themselves,
