A mutagen is a chemical or physical agent that has the ability to change our genetic code in a harmful way. The change in the genetic code is called a mutation, and throughout our lifetime we actually accumulate many mutations within our cells. And our body has the ability to recognize and repair these mutations. However, if some of these mutations escape repair, they can cause a normal cell to be transformed to become a tumor cell. Therefore, mutations are actually associated with the development of cancer.

Chemical Mutagen – an overview | ScienceDirect Topics – Chemical Mutagen Chemical mutagens are standard tools for mutagenesis in a variety of organisms, and they are a primary means of creating mutations in phenotype-based screens in most genetic systems. From: Handbook of Stem Cells, 2004There are different chemical mutagens. Some of them are nitrous acid, acridines, proflavins, certain pesticides, lead. These mutagens causes various symptoms in human which may be paralysis, initially eventually causes death on high exposure. Even certain powerful medicine if over taken may act as mutagens.Chemical mutagen definition Chemicals that cause mutations if cells are exposed to them at high frequencies or for prolonged periods of time. Chemical mutagens cause a change in DNA that alters the function of proteins, as a result, cellular processes are impaired. Naturally occurring mutagen definition

Mutagens Flashcards | Quizlet – Chemical Mutagen Chemical mutagens are standard tools for mutagenesis in a variety of organisms, and they are a primary means of creating mutations in phenotype-based screens in most genetic systems. From: Handbook of Stem Cells, 2004A mutagen is a chemical or physical phenomenon, such as ionizing radiation, that promotes errors in DNA replication. Exposure to a mutagen can produce DNA mutations that cause or contribute to diseases such as cancer.The chemical agents which may cause mutation are called mutagens. Most of them are also carcinogens. The following figure shows the chemical structures of a few potent mutagens. Figure 7-F-7 explains the mechanism of mutation by 5-bromouracil.
