In the 1920s Muller discovered that X-rays caused mutation in Drosophila. In a related series of experiments in the 1940s, Charlotte Auerbach discovered that chemicals-she used nitrogen mustards-have a similar effect. A new chemical food additive is developed by a cereal manufacturer. Why do we test for its ability to induce mutation?
A) We worry that it might cause mutation in cereal grain plants.
B) We want to make sure that it does not emit radiation.
C) We want to be sure that it increases the rate of mutation sufficiently.
D) We want to prevent any increase in mutation frequency.
E) We worry about its ability to cause infection.

Question

Quizplus · Accepted Answer

Testing for the ability to induce mutation is important to prevent any increase in mutation frequency that may have negative effects. If a chemical is found to increase mutation rates, it may lead to the development of genetic disorders or diseases. Testing for mutation-inducing properties is a crucial step in ensuring the safety of new chemical food additives.
