Beadle and Tatum used which of the following organisms to support their one gene - one enzyme concept?

a. escherichia coli

b. drosophila

c. neurospora

d. salmonella

e. homo sapien

Neurospora.

Explanation:

Beadle and Tatum experiment shows one gene one enzyme hypothesis. According to this, a single enzyme is encoded by each gene. This idea is not accepted in today's world.

Beadle and Tatum performed experiment on the neurospora. They chosed neurospora in their experiment because neurospora shows the fast life cycle with alternation of generation. The genetic experiments can be easily performed on neurospora.

Thus, the correct answer is option (c).
