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.

What are mutagens and what does it do?
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
If you have just learned that a chemical you work with is a mutagenwhat effect does this chemical have?
A mutagen is a substance that can alter the DNA of an organism, potentially leading to genetic mutations. This can result in harmful changes in the genetic material, which may lead to negative effects like increased risk of cancer or other health issues. It is important to take precautions when working with mutagens to minimize exposure and potential risks.
How can mutagens cause genetic mutations in spite of your body DNA repair enzymes?
Mutagens cause a change in DNA and by this way they can produce mutant DNA repair enzymes.
Fill in the blank Environmental causes of mutations are called?
mutagens
Substances used to increase the rate of mutations?
Mutagens are substances that increase the rate of mutations by altering DNA, causing changes in the genetic material of an organism. Common mutagens include UV radiation, certain chemicals like ethidium bromide, and some viruses. These mutagens can lead to errors in DNA replication, resulting in genetic mutations.
What are the main types of mutagens?
physical mutagens-e.g. uv radiation chemical mutagens-e.g. nitrous acid biological mutagens-e.g. viral infection
How does mutagens enter a human's body?
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.

Which accurately describes the relationship between cancer risk and exposure to mutagens?
The relationship between cancer risk and exposure to mutagens is generally positive, as mutagens can cause changes in the DNA that lead to mutations, which are a key factor in cancer development. Increased exposure to mutagens, such as certain chemicals, radiation, or infectious agents, elevates the likelihood of acquiring mutations that may disrupt normal cell function and promote uncontrolled cell growth. Consequently, understanding and minimizing exposure to known mutagens is crucial in cancer prevention strategies.

What type of chemicals cause mutations?
Mutagens D2

Mutagens cause a change in DNA and by this way they can produce mutant DNA repair enzymes.
Explain how mutagens can cause genetic mutations in spite of your body's DNA repair enzymes?
Mutagens are substances that can alter DNA, leading to mutations. Some mutagens can overwhelm the repair machinery in your cells, causing errors to go unrepaired. Additionally, some mutations occur in regions of DNA that are less effectively repaired by the cell's machinery.
