Question

Suppose you do a mutant screen for Neurospora mutants unable to grow on minimal medium unless they are supplemented with an amino acid we'll call 'A' Based on their molecular structures. you surmise that two molecules. x and Y, are intermediates in the biochemical pathway for the synthesis of A, but you are unsure which of the following pathways may be correct (a) x->Y->A (b) Y->x->A You find two classes of mutants that require A for growth. Class 1 grows on minimal medium supplemented with A but not with x or Y. Class 2 grows on minimal medium supplemented with A or x but not with Y. Which of the pathways (a) or (b) do these data support?

Step 1

" Based on their molecular structures, you surmise that two molecules, X and Y, are intermediates in the biochemical pathway for the synthesis of A, but you are unsure which of the following pathways may be correct: (a) X $\rightarrow$ Y $\rightarrow$ A (b) Y Show more…
