Germicidal ultraviolet (UVC) light kills cells by damaging their DNA. The light initiates a reaction between two molecules of thymine, one of the bases that make up DNA. UV light at this wavelength (shortwave UV or UVC) causes adjacent thymine molecules on DNA to dimerize. The resulting thymine dimer is very stable. If enough of these defects accumulate on a microorganism's DNA its replication is inhibited, thereby rendering it harmless.
The longer the exposure to UVC light, the more thymine dimers are formed in the DNA. If cellular processes are disrupted because of DNA damage, the cell cannot carry out its normal functions. If the damage is extensive and widespread, the cell will die.

Does UV light kill viruses?
Yes
Can uv light kill candida?
If UV kill pathogen microorganisms(GERMS,BACTREIAS,VIRUSES,FUNGI) in UV water filtering systems,it can surely kill yeasts and fungi in the blood submitted to the UV irradiation .All we need is a NEW DR BECK WHO WILL DESIGN A DIALYSIS STYLE machine in which the blood WILL FLOW from the right hand to the left or the opposite after being submitted during his flow in a transparent tube to UV irradiations.
What is ultraviolet radiation used for?
UV light can be used to identify objects that is normally invisible to the naked eye (ie. stains) UV light can also be used to kill germs. production of vitamin D enables certain anti-cancer functions in cells
Does UV light kill bed bugs?
UV, depending upon concentration/duration, can kill anything living.
Can light kill germs in water?
very well
How does a toothbrush sanitizer function?
It works by killing germs i.e. bacteria, viruses, fungi and protozoa. There are two main types of toothbrush sanitizers for consumers. One type uses UV light to kill germs. The other type, which is more effective, uses steam to kill germs. Given that some germs can make us sick, killing the germs found on the toothbrush therefore sanitizes the toothbrush.
How long does it take for UV light to kill bacteria?
it doesnt
