Question

Beadle and Tatum did classical experiments on Neurospora crassa to prove

• A. One gene produces one enzyme.
• B. One enzyme can correct one gene.
• C. Many genes produce one enzyme.
• D. None of the above.

Answer 1

The correct option is A One gene produces one enzyme.

Beadle and Tatum did classical experiments on Neurospora crassa to prove that in a multistep biochemical pathway, each step is controlled by different enzymes and each of these enzymes is encoded by a specific gene. This is called as one gene one enzyme hypothesis.

So, Option A is the correct answer.
