摘　　要：The impacts of Ultraviolet (UV) radiation on the human body have received increased attention in previous years. The impacts are comprised of a series of illnesses, burns, and modifications in the genetic structures. Therefore, the current study aimed to identify the effect of sunscreens on yeast to prevent ultraviolet damage. The study uses two sunscreens with different sun protection factors to show how they differently protect the cells from the wrath of UV light. The experiment involves the use of yeast as the test organism since yeast has DNA that is used for reproduction by budding. UV light affects the growth of the bacteria and the limiting factor with the sunscreens. Six Petri dishes with agar were inoculated with yeast solution and put under different conditions and the growth results will be obtained. The experiment also showed how different clothes protect human from the UV radiations.The impacts of Ultraviolet (UV) radiation on the human body have received increased attention in previous years.
