    Mutagen - Wikipedia

    • In 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. As many mutations can cause cancer in animals, such mutagens can therefore be carcinogens, although not all necessarily are. All mutagens have characteristic mut… 展开

    Discovery

    The first mutagens to be identified were carcinogens, substances that were shown to be linked to cancer. Tumors were described more than 2,000 years before the discovery of chromosomes and DNA; in 500 B.C., the Greek … 展开

    Difference between mutagens and carcinogens

    Mutagens are not necessarily carcinogens, and vice versa. Sodium azide for example may be mutagenic (and highly toxic), but it has not been shown to be carcinogenic. Meanwhile, compounds which are not directly mutageni… 展开

    Difference between mutagens and DNA damaging agents

    A DNA damaging agent is an agent that causes a change in the structure of DNA that is not itself replicated when the DNA is replicated. Examples of DNA damage include a chemical addition or disruption of a … 展开

    What are the different types of mutagenesis?
    Types of mutations that can be introduced by random, site-directed, combinatorial, or insertional mutagenesis. In molecular biology, mutagenesis is an important laboratory technique whereby DNA mutations are deliberately engineered to produce libraries of mutant genes, proteins, strains of bacteria, or other genetically modified organisms.

    What is DNA mutagenesis?
    DNA mutagenesis occurs spontaneously in nature or as a result of mutagens (agents predisposing to alter DNA). Furthermore, molecular genetic techniques, such as polymerase chain reaction (PCR), have revolutionized how mutations are obtained and studied.

    How is mutagenesis achieved?
    It can also be achieved experimentally using laboratory procedures. A 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.

    What is induced mutagenesis?
    Mutagenesis is the process of producing a mutation. If it occurs in nature without the action of a known mutagen, it is called spontaneous mutagenesis and the resulting mutations are spontaneous mutations. If a mutagen is used, the process is called induced mutagenesis. Mutations can be categorized in several ways.

    Are mutagens a carcinogen?
    They can affect the transcription and replication of the DNA, which in severe cases can lead to cell death. The mutagen produces mutations in the DNA, and deleterious mutation can result in aberrant, impaired or loss of function for a particular gene, and accumulation of mutations may lead to cancer. Mutagens may therefore be also carcinogens.

    Are mutagens mutagenic?
    Many mutagens are not mutagenic by themselves, but can form mutagenic metabolites through cellular processes, for example through the activity of the cytochrome P450 system and other oxygenases such as cyclooxygenase. Such mutagens are called promutagens.
