		Discussion Our results were as expected. Since UV radiation inhibits cytoskeletal function, we observed improper cell divisions, and no gut formation in all irradiated embryos. Control samples looked normal, confirming that our experiment was performed correctly. No significant differences could be observed between samples 2, 3 and 4, where irradiation took place at different times. For this reason, we conclude that the time of irradiation, before or after fertilization, does not make a difference in the overall effect on the embryos. Irradiation at any time does not allow embryos to develop normally since it disrupts cytoskeletal function, which is crucial to proper embryonic development.
