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.

∙ 12y agoUV 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.

How are humans adapted to UV rays?
UV-A helps us form vitamin D.UV-B and more energetic radiation causes cancer, mutation, and cataracts.
Why does UV light affect Escherichia coli?
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
Does UV light kill viruses?
UV rays (Ultra violent rays) kills plants and humans.
What two factors must be present in the bacteria environment for you to see the green color?
arabinose and UV light
Is UV light the same as fluorescent 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.
Why do hairdressers have uv light?
The UV light causes DNA damage in bacteria, so it is used to sterilize the equipment.
Does UV light cause mutation?
yes uv does cause mutations by introducing distortions in the form of thymine thymine dimers
What is the effect of UV light on bacteria growth?
Kills it
What wavelength of uv light causes thymine dimmers?
UV-c
Does UV light sterilize utensils?
UV light radiation kills bacteria and can sterilize utensils (UV rays are used to sterilize goggles in the laboratory, for example.
How are humans adapted to UV rays?
UV-A helps us form vitamin D.UV-B and more energetic radiation causes cancer, mutation, and cataracts.
Why does UV light affect Escherichia coli?
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
How does ultraviolet light kill bacteria?
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.
Does UV light kill bacteria?
yes, it does it burns it until it goes away.
What kind of light causes skin cancer?
Ultraviolet, or UV rays.
What causes the outer petals of a rosebud to turn brown?
UV light
Does UV light kill viruses?
UV rays (Ultra violent rays) kills plants and humans.
