Quizplus · Accepted Answer

Blocking mRNA synthesis means that the organism would not be able to produce new proteins. This would eventually lead to cell death and ultimately death of the organism. In fact, α-amanitin is one of the most lethal toxins known and is responsible for the majority of deaths from mushroom poisoning. Therefore, the correct answer is D.
