Successful survival and division of bacteria is observed as growth of colonies on an agar plate. This strain of bacteria can grow colonies on minimal medium as long as it is supplemented with compound 1. You are in a lab that has isolated several mutants of this strain.

Consider the biochemical pathway shown here. Suppose that a strain of bacteria must synthesize compound 4 to survive and
divide. Successful survival and division of bacteria is observed as growth of colonies on an agar plate. This strain of bacteria can grow
colonies on minimal medium as long as it is supplemented with compound 1.
You are in a lab that has isolated several mutants of this strain. You find that these mutants cannot grow on minimal medium
supplemented with compound 1, though they can grow colonies if supplemented with compound 4. Considering what you know about
the Beadle-Tatum experiments, which of the following statements would be one that should be true?
A mutant strain lacking enzyme A will likely only grow colonies on minimal medium supplemented with compound 4.
Compounds 2, 3, and 4 are likely encoded by genes that have been mutated in this strain of bacteria.
O I.
The original strain of bacteria most likely lacks enzymes A, B, and C.
II.
A mutant strain lacking enzyme C will likely only grow on minimal medium if it is supplemented with compound 4.
