What is the term for an agent, such as a chemical or radiation, that increases mutation rates?

The term for an agent that increases mutation rates is known as a mutagen. Mutagens are substances or factors that cause changes in the DNA sequence, which can lead to mutations. These mutations can alter gene function, potentially leading to various outcomes, including cancer or genetic disorders.

By definition, mutagens can be physical agents like radiation or chemical substances that interact with DNA. Their role is significant in the study of genetic mutations, as increased mutation rates can have profound implications for health and disease. Understanding mutagens is crucial in fields such as genetics, toxicology, and cancer research because they help in assessing risks associated with exposure to certain chemicals or radiation and in the development of strategies for prevention and treatment.
