Question

art B Bacteria are growing in an open protein shake you placed in the refrigerator three weeks ago. The shake's ingredients include glycine ar sucrose and fructose-sugars the bacteria are capable of catabolizing. Assuming the gene expression necessary for all four of these fun O Glycine will bind to the repressor, and the structural genes for synthesizing glycine will be expressed. Leucine wilNOT bind to the repressor, and the structural genes for synthesizing leucine will NOT be expressed O Fructose will bind to the repressor, and the structural genes for catabolizing fructose will NOT be expressed O sucrose will bind to the repressor, and the structural genes for catabolizing sucrose wil be expressed Hints My Answers Give Up Review Part Submit incorrect; Try Again; 5 attempts remaining Because leucine is present in the shake, it wil bind to the repressor Part C O Ask me anything

Explanation / Answer

It work is similar to the lac operon found in the bacteria.. When lactose is present allo-lactose binds to the repressor and intiate the lac operon.. Similarly, as the sucrose is present in the protein shake I has to catabolized.. So sucrose will binds to the repressor and the structural gene will be expressed to the form the sucrose catabolizing enzymes..!! The answer is (4).
