Base Analogue Incorporation 2. The lack of this DNA at some point of replication can cause a genetic disease. Some of the most common are: Radiation - One of the first known mutagens, radiation is a potent inducer of mutations. Some of the important chemical mutagens are listed in Table 21.5. Spontaneous mutations originate without any known reasons, meaning, occur randomly. The goal of the IMSR is to assist the international scientific community in locating and obtaining mouse resources for research. Analysis of the mutations induced by conazole fungicides in vivo During the period studied by the Advisory Committee, there was considerable debate among the scientific community over both the extent and the consequences of radiation-induced mutations. Induced mutations: Mutations can be induced by exposing organisms (or cells) to a variety of treatments. Induced mutations are alterations in the gene after it has come in contact with mutagens and environmental causes. Use of log-linear analysis to construct explanatory models for TDBP Numerous lines of evidence have established that NNK induces several kinds of cancer in different animal models, and that the underlying mechanisms are carcinogen-mediated DNA mutations and abnormal signaling pathways activated by associated receptors, such as 7 nicotinic acetylcholine receptor (7-nAChR) and -adrenergic receptor (-AR .
