List of common mutagens

In genetics, a mutagen is a physical or chemical agent that permanently changes genetic material, usually DNA, in an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer in animals, such mutagens can therefore be carcinogens, … Meer weergeven The first mutagens to be identified were carcinogens, substances that were shown to be linked to cancer. Tumors were described more than 2,000 years before the discovery of chromosomes and DNA; in 500 B.C., the Meer weergeven Mutagens can cause changes to the DNA and are therefore genotoxic. They can affect the transcription and replication of the DNA, which in severe cases can lead to cell death. The mutagen produces mutations in the DNA, and deleterious mutation … Meer weergeven Antioxidants are an important group of anticarcinogenic compounds that may help remove ROS or potentially harmful chemicals. … Meer weergeven Many mutagens are highly toxic to proliferating cells, and they are often used to destroy cancer cells.
