In toxicology, genotoxicity is assessed using a variety of genotoxicity tests. These tests evaluate the potential of substances to cause DNA damage. Common assays include the Ames test, which detects mutations in bacteria, the Comet assay for evaluating DNA strand breaks, and the Micronucleus test that measures chromosomal damage in cells. These tests are essential tools for regulatory agencies to assess the safety of chemicals, pharmaceuticals, and environmental pollutants.
