Question

The Ames test demonstrates that a chemical is

A) carcinogenic.
B) carcinogenic in humans.
C) carcinogenic in Salmonella.
D) mutagenic in humans.
E) mutagenic in Salmonella.

Answer 1

The Ames test is a biological assay used to assess the mutagenic potential of chemicals. It involves exposing a strain of Salmonella bacteria to a chemical compound and counting the number of mutants that regain the ability to synthesize histidine. This test serves as an indicator of mutagenicity and can help identify potential carcinogens.

Step-by-step explanation:

The Ames test is a biological assay used to assess the mutagenic potential of chemical compounds. It utilizes a strain of Salmonella bacteria that is unable to synthesize its own histidine due to a mutation. The test involves exposing the bacteria to a chemical compound and then counting the number of mutants that regain the ability to synthesize histidine. This test serves as an indicator of mutagenicity and can be used to identify potential carcinogens.
