Ultraviolet light causes mutation. UV light is of higher energy than visual light and this is enough energy to cause damage in the DNA of microorganisms or even animal cells. UV light is what causes sunburns. The cells of the skin usually die due to damage to its DNA and peel off just as microorganisms die.
UV radiation is responsible of lesions in bacteria and eukaryote cells, by at least two different means :
- alteration of genetic code, preventing reproduction or leading to cancer
- alteration of cell's constituents like the membrane, the enzymes... resulting in perturbations of metabolism wich can be fatal.
UV could potentially kill bacteria because UV light waves are of high energy, and can break the bonds in DNA, causing problems including death.
UV light kills microorganisms, such as fungus and molds.
yes uv does cause mutations by introducing distortions in the form of thymine thymine dimers
yes, of course it can.
it doesnt
UV-A helps us form vitamin D.UV-B and more energetic radiation causes cancer, mutation, and cataracts.
UV lights are lethal and cause mutation in cell of E.coli during DNA replication which lead to the death of microbes. It enhance the formation of thymine dimer which cause mutation
UV rays (Ultra violent rays) kills plants and humans.
arabinose and UV light
The UV light is different to that of fluorescent light. The UV originates from the sun. The latter one does not.No, it is not. UV is different.
The UV light causes DNA damage in bacteria, so it is used to sterilize the equipment.
yes uv does cause mutations by introducing distortions in the form of thymine thymine dimers
Kills it
UV-c
UV light radiation kills bacteria and can sterilize utensils (UV rays are used to sterilize goggles in the laboratory, for example.

UV light causes dimerisation between Cytosine bases in DNA (causing it to mutate). As bacteria only have small genomes, mutations will have a lethal effect a lot more commonly than if it happened to a person.
yes, it does it burns it until it goes away.
