Mutagens may be of physical, chemical, or biologic origin.
Examples of physical mutagens include Ultraviolet rays, radioactivity, and over high temperature.
Examples of chemical mutagens include nicotine, pesticides, and methane.
Examples of biologic mutagens include bacteria and viruses.
Gene mutation
Positive mutation
Negative mutation
Neutral mutation
physical mutagens-e.g. uv radiation
chemical mutagens-e.g. nitrous acid
biological mutagens-e.g. viral infection
Things that cause mutations such as heat, radiation, etc..

HEMOGLOBIN
Mutagens cause changes, or mutations, in genetic material like DNA. Some mutagens include:Chemical agents like benzene can metabolize with animal cells to create mutagens.X-rays can damage DNA.Some bacteria and viruses can inhibit DNA repair mechanisms.Carcinogens are mutagens that have the effect of causing cancer.

In genetics, a mutagen (Latin, literally origin of change) is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations cause cancer, mutagens are therefore also likely to be carcinogens. Not all mutations are caused by mutagens: so-called "spontaneous mutations" occur due to spontaneous hydrolysis, errors in DNA replication, repair and recombination.Contents[hide] 1 Discovery of mutagens2 Effects of mutagens3 Types of mutagens 3.1 Physical mutagens3.2 DNA reactive chemicals3.3 Base analogs3.4 Intercalating agents3.5 Metals3.6 Biological agents4 Protection against mutagens5 Mutagen test systems 5.1 Bacterial systems5.2 Yeast5.3 Drosophila5.4 Plant Assays5.5 Cell culture assay5.6 Chromosome check systems5.7 Animal test systems6 Use of mutagen in anti-cancer therapy7 Mutagens in fiction8 See also9 References

mutagens.
Mutagens can enter the human body through various routes such as inhalation, ingestion, and skin contact. Once inside the body, mutagens can disrupt DNA and lead to mutations that can potentially contribute to the development of cancer. It is important to minimize exposure to mutagens to reduce the risk of negative health effects.

Mutagens D2
Mutagens cause a change in DNA and by this way they can produce mutant DNA repair enzymes.
