Mutagenesis Research Chemicals Overview
Gene mutation is ubiquitous in the biological world. Gene mutation may occur in both lower organisms, higher animals and plants, and people. Gene mutation exists widely in natural species. Mutations are caused by errors in DNA replication (especially meiosis) or incorrect repair of DNA damage (such as exposure to radiation or carcinogens). Induced mutation refers to the use of artificial measures to induce the phenotypic or genetic information of organisms to change, which is often used in the excavation of functional genes, the improvement of crop germplasm resources and the cultivation of new excellent varieties. According to the different measures taken, induced mutation can be divided into physical mutagenesis, chemical mutagenesis, aerospace mutagenesis, biological mutagenesis, etc. Chemical mutagenesis has the characteristics of convenient use and low cost. Chemical mutagens refer to the chemical substances that cause mutation. Common chemical mutagens include base analogues (such as 5-bromo-uracil), alkylating agents (such as EMS), antibiotics, etc.
