Which of the following tests is commonly used to determine the carcinogenic potential of a chemical?
A
Ames test
B
Benedict's test
C
Limewater test
D
Flame test
Verified step by step guidance1
Understand that the question asks about a test used to determine the carcinogenic potential of a chemical, which means assessing whether a chemical can cause mutations that may lead to cancer.
Recall that the Ames test is a biological assay that uses bacteria to test whether a given chemical can cause mutations in the DNA, which is directly related to carcinogenic potential.
Recognize that Benedict's test is used to detect reducing sugars, Limewater test is used to detect carbon dioxide, and Flame test is used to identify metal ions based on flame color; none of these are related to testing carcinogenicity.
Therefore, identify the Ames test as the correct and commonly used test for assessing the mutagenic and carcinogenic potential of chemicals.
Summarize that the Ames test involves exposing specific strains of bacteria to the chemical and observing whether mutations occur, indicating potential carcinogenicity.
