Beadle and Tatum's Mutated Neurospora Were Unable to Grow on Minimal

question 10

Multiple Choice

Beadle and Tatum's mutated Neurospora were unable to grow on minimal media plus metabolites A or B,but did grow on minimal media plus metabolites C and D,indicating enzyme 2 was missing from the hypothetical pathway.

• A) If only enzyme 1 was missing,then growth would occur with just metabolite B.
• B) From the limited data given here,enzyme 1 could also be missing from the original experiment.
• C) Any minimal media with metabolite D should grow the Neurospora without revealing if the strain contains or lacks enzymes 1,2 or 3.
• D) Failure to grow on minimal media possessing metabolites A,B and C reflects a lack of enzyme 3.
• E) All of the choices are correct.
