How do mutations potentially cause harm
WebSo far, scientists have identified a number of ways in which genetically engineered organisms could potentially adversely impact both human health and the environment. Once the potential harms are identified, the question becomes how likely are they to occur. The answer to this question falls into the arena of risk assessment.

WebThe mutation producing the deleterious allele may keep arising in the population, even as selection weeds it out. For example, neurofibromatosis is a genetic disease causing tumors of the nervous system. WebFor example, when a cell divides, it makes a copy of its DNA — and sometimes the copy is not quite perfect. That small difference from the original DNA sequence is a mutation. 2.
