Mutagen - Wikipedia
WebIn genetics, a mutagen is a physical or chemical agent that permanently changes genetic material, usually DNA, in an organism and thus increases the frequency of mutations above the natural background level.
Mutagen | DNA damage, genetic mutations, carcinogens
Webmutagen, any agent capable of altering the genetic constitution of a cell by changing the structure of the hereditary material, deoxyribonucleic acid (DNA). Many forms of electromagnetic radiation ( e.g., cosmic rays, X rays, ultraviolet light) are mutagenic, as are a variety of chemical compounds .
Mutagen - Definition and Examples - Biology Online Dictionary
WebJul 24, 2022 · A mutagen is a substance or agent that causes DNA impairment that results in the alteration of the DNA sequence. This alteration of the DNA sequence is known as mutation. Any agent causing mutation is called mutagen. Mutagens can be physical mutagens, chemical mutagens, or biological mutagens. The ability of a substance to …
Mutagen - National Human Genome Research Institute
WebMay 17, 2019 · A mutagen is a chemical or physical agent capable of inducing changes in DNA called mutations. Examples of mutagens include tobacco products, radioactive substances, x-rays, ultraviolet radiation and a wide variety of chemicals. Exposure to a mutagen can produce DNA mutations that cause or contribute to certain diseases.
Mutagens and carcinogens (video) | Mutations | Khan Academy
WebMutagens and carcinogens can cause DNA damage, affecting protein production. Mutagens, either endogenous or exogenous, increase genetic mutation probability. Endogenous mutagens, like reactive oxygen species (ROS), are produced by the body. Exogenous mutagens include intercalators and base analogs.
Mutagens- Definition, Types (Physical, Chemical, Biological)
WebAugust 3, 2023 by Dibyak Kapali. Edited By: Sagar Aryal. A mutagen is a physical or chemical agent that can cause mutations in DNA and raises their frequency above natural background levels. They may directly damage DNA due to their actions, which most frequently leads to replication errors.
Mutagenesis - Wikipedia
WebA mutagen is a mutation-causing agent, be it chemical or physical, which results in an increased rate of mutations in an organism's genetic code. In nature mutagenesis can lead to cancer and various heritable diseases , and it is also a driving force of evolution .

WebAs noted by Charlotte Auerbach [1976], the discoveries of Muller and Stadler caused X-ray mutagenesis to dominate the field of genetics for the next 20 years, providing insight into genetic recombination, types of mutations, and the nature of the gene.
Environmental Mutagens, Cell Signalling and DNA Repair
WebThese agents are known as mutagens, and they act by directly altering a cell's DNA sequence. Many mutagens, by virtue of their size or structure, can slip through both cell and nuclear membranes ...
Mutagen | SpringerLink
WebA mutagen is a physical, chemical, or biological agent able to increase the occurrence of mutations above the spontaneous level. Mutations produced by the action of mutagens are called induced mutations. The effect of most mutagens is due to their ability to modify a particular nucleic acid base or to become incorporated into the nucleic acid.
