What kind of damage can ultraviolet (UV) radiation do at the cell level? cell wall damage mitochondrial damage DNA damage endoplasmic reticulum damage QUESTION 2 What kind of larger problem(s) can that cellular damage sometimes lead to (in humans, for example)? sunburn skin cancer premature skin aging all of the above QUESTION 3 What are possible cellular responses to moderate and severe damage, such as from high exposure to UV radiation? DNA replication cell death cell division normal cells don't respond to damage so no change is expected

What part of the cell does UV damage affect most? a. cell membrane b. DNA c. proteins d. lipids e. sugars Should one protect the eyes and skin from exposure to UV? What are your predictions on the resistance of endospore forming bacteria to non-spore forming bacteria? Can't remember? Go to the cell chapter in your text; find endospores. Prions are infectious particles devoid of any nucleic acid, containing only protein. What is your prediction on the ability of prions to withstand UV sterilization? What are the wavelengths of UV-C light? How many US deaths per year are due to tanning beds? How is the University of Pennsylvania using UV light in their hospitals? What is the most significant pathogen in the group of bacteria that are beta hemolytic streptococci? What is (use your text book or notes) i. alpha hemolytic ii. beta hemolytic iii. gamma hemolytic?
