Ultraviolet radiation may give you sun burns, but it also can be used to disinfect edibles, water, hospitals, etc. (“How Does UV”) You can kill microorganisms in a variety of ways, including the right amounts of humidity, energy, water, air, or light. (Maczulak 229) A germ’s existence is counted in minutes, so it relies on reproduction. Damaging the DNA would kill it, because the bacteria wouldn’t be able to split or reproduce after it absorbs the UV rays. When the UV reaches the DNA, it breaks down its component, helix. UV can be more effective on some bacteria more than others, because some have built in defense against it. If it is exposed longer, it could eventually die out. The odds of it building resistance in that long amount of exposure is minimal. (“How Does UV”)
Then again, there were mutations in cells from solar radiation in the Archean Era. In one experiment, they tested different strains of Bacillus, and the resistance differed because some adapted. This follows Darwin’s theory of evolution, …show more content…

They used the sun for energy through photosynthesis. At first, it was incompatible for any potential life until the atmospheric array of nitrogen, oxygen, carbon, and hydrogen made it suitable for life. It led to the creation of the genetic code in DNA and RNA and the proteins that process it. There were extreme conditions on Earth at the time, like radiation, so the bacteria must have had to adapt. (Lerner 2011)
Changes in enzymes can make bacteria immune to the antibiotic it’s fighting. Agar is like a fertilizer for the bacteria to grow and nourish off of. (Lerner 2007) Using sheep blood agar, one study used ultraviolet radiation on antibiotic resistant bacterial strains of Staphylococcus and Enterococcus. The antibiotic resistant bacteria were completely killed off within 120 seconds by the radiation. (“The effects
