A chemical or physical agent able to change the genetic material in cells (see "Do all toxic chemicals cause mutations?", Understanding Toxic Substances)
Chemical or type of ionizing radiation that can cause inheritable changes in the DNA molecules found in the genes of organisms (mutations) Also see carcinogen, mutation, and teratogen
Any agent capable of altering a cell's genetic makeup by changing the structure of the hereditary material, DNA. Many forms of electromagnetic radiation (e.g., cosmic rays, X rays, ultraviolet light) are mutagenic, as are various chemical compounds. The effects of some mutagens are increased or suppressed in some organisms by the presence of certain other, nonmutagenic substances; oxygen, for example, makes cells more sensitive to the mutagenic effects of X rays
An agent that changes the hereditary genetic material which is a part of every living cell Such a mutation is probably an early step in the sequence of events that ultimately leads to the development of cancer
An agent that causes a permanent genetic change in a cell other than that which occurs during normal growth Testing to determine mutagenicity is one component of assessing the potential chronic toxicity of pesticides and other chemicals
agent that induces a mutation within an organism, such as X-rays, gamma rays, neutrons, and certain chemicals such as carcinogens KP is an agent capable of inducing a mutation (a change that alters the sequence or chemistry of bases in the DNA molecule) in the genetic material of an organism [CUB]
