Genotoxicity is the property of chemical agents that damage the genetic information within a cell causing mutations, which may lead to cancer. While genotoxicity is often confused with mutagenicity, all mutagens are genotoxic, but some genotoxic substances are not mutagenic. The alteration can have direct or indirect effects on the DNA: the induction of mutations, mistimed event activation, and direct DNA damage leading to mutations. The permanent, heritable chang… WebOct 30, 2014 · genotoxicity and mutagenicity; dose-response and ... induction, along with the induction of cytotoxicity, apoptosis, compensatory cell proliferation, changes in gene expression, hormonal status ( etc.) in comparison with the production of preneoplastic lesions and then tumors in the
