- Open QuestionIn this chapter, we focused on how gene mutations arise and how cells repair DNA damage. At the same time, we found opportunities to consider the methods and reasoning by which much of this information was acquired. From the explanations given in the chapter,How do we know that DNA repair mechanisms detect and correct the majority of spontaneous and induced mutations?

From the explanations given in the chapter,How do we know that certain chemicals and wavelengths of radiation induce mutations in DNA?
- Open Question
