Abstract

Unscheduled DNA synthesis occurred in both male and female pronuclei of the mouse zygote in response to irradiation with ultraviolet light, indicating a capacity for excision repair. Furthermore, damage to DNA of the male gamete before fertilization can be repaired after the sperm enters the egg cytoplasm.
