Nettet5. jan. 2024 · Mutagen Causes of Mutations. Apart from mutations occurring spontaneously, certain environmental factors can cause mutations in DNA as well. NettetIt typically uses a strain of bacteria, such as Salmonella typhimurium, that has a mutation in a gene called hisG, rendering the bacteria unable to produce histidine on its own. The test measures the ability of a chemical to cause reverse mutations (reversions) in the hisG gene, thereby allowing the bacteria to grow in the absence of histidine. NettetGametic mutations occur in the reproductive organs (they occur in the testes of males or ovaries of females), usually during meiosis, when the gametes (eggs and sperm) are being formed.
