Which of the following regarding the Ames test is true?

It is used to identify newly formed auxotrophic mutants.
It is used to identify mutants with restored biosynthetic activity.
It is used to identify spontaneous mutants.
It is used to identify mutants lacking photoreactivation activity.

Respuesta :

Answer:

Option (2).

Explanation:

Ames test is used to identify the mutageneicity of the compound. The bacteria are treated with chemicals in the nutritive environment to determine whether the substance can acts as a mutagen or not.

The bacteria that can restore the biosyntheic activity in the environment can be considered as mutagen. The mutant bacteria can be easily identified in the Ames test.

Thus, the correct answer is option (2).
