Which of the following would be an example of a chemical mutagen?ANSWERUV radiationArsenicX-raysTransposons

To identify which option is an example of a chemical mutagen, let's analyze each option:

1. UV radiation: This is a form of non-ionizing radiation and primarily causes damage through the formation of pyrimidine dimers in DNA. It is not classified as a chemical mutagen.

2. Arsenic: This is a chemical element that can disrupt various cellular processes and has been shown to induce mutations. Thus, arsenic can be considered a chemical mutagen.

3. X-rays: These are a type of ionizing radiation, which can also cause mutations but do so through physical means rather than through a chemical reaction. Therefore, X-rays are not classified as chemical mutagens.

4. Transposons: These are genetic elements that can change their position within the genome, potentially causing mutations. While they can induce mutation, they are not classified as chemical mutagens.

Conclusion

The correct answer for a chemical mutagen among the options provided is Arsenic.
