Mutagenicity
Mutagenicity
Mutagenicity (/mjuːtədʒɪˈnɪsɪti/) refers to the ability of a physical or chemical agent to cause mutations in the genetic material of an organism.
Etymology
The term "mutagenicity" is derived from the Latin word "mutare", meaning to change, and the Greek suffix "-gen", meaning producer of.
Definition
Mutagenicity is a property of certain chemicals or radiation, which can alter the structure of DNA and lead to genetic mutation. This can potentially lead to a variety of diseases, including cancer.
Types of Mutagens
There are several types of mutagens, including:
- Chemical mutagens: These include certain chemicals that can cause DNA damage. Examples include benzene, formaldehyde, and certain pesticides.
- Physical mutagens: These include certain types of radiation, such as ultraviolet light and X-rays, which can cause DNA damage.
- Biological mutagens: These include certain viruses and bacteria that can cause DNA damage.
Related Terms
- Genotoxicity: This is a related term that refers to the ability of a substance to damage genetic information within a cell, leading to mutations.
- Carcinogenicity: This refers to the ability of a substance to cause cancer. Many mutagens are also carcinogens, but not all carcinogens are mutagens.
- Teratogenicity: This refers to the ability of a substance to cause birth defects. Some mutagens are also teratogens.
