Question

According to Beadle and Tatum's hypothesis, how many genes are necessary for this pathway?

- 0
- 2
- 1
-3
- It cannot be determined from the pathway.

Answer 1

According to Beadle and Tatum's hypothesis, 3 genes are necessary for the arginine biosynthesis pathway.

Step-by-step explanation:

According to Beadle and Tatum's hypothesis, each mutant in the arginine biosynthesis pathway is defective in a different gene encoding a different enzyme. Therefore, based on their experiments, it can be determined that 3 genes are necessary for this pathway.
