mutagény
Mutagény, often referred to as a mutagen, is an agent that increases the frequency of genetic mutations by altering DNA. Mutagens can act at the level of DNA sequence or structure and may affect germline cells, somatic cells, or both. They can be chemical, physical, or biological.
Chemical mutagens include alkylating agents that modify bases, base analogs that substitute for natural nucleotides, and
Mutagenicity is assessed through assays such as the Ames test, which uses bacteria to detect mutations that
Exposure to mutagens is regulated for human health and environmental protection. Long-term exposure to certain mutagens,
