Respuesta :

Answer: its A

Explanation:

Answer: Option A

Explanation:

One gene one enzyme hypothesis was proposed by George Wells Beadle in which he stated that one gene directly affects the production of the  single enzyme.

This consequently affects the individual step in the whole metabolic pathway.  

So, a mutation in the single gene will lead to the production of the faulty protein. The step of the metabolism will be affected in which the faulty enzyme will participate.
