What is a DNA repair enzyme activated by visible light?
DNA photolyase
What is the result if DNA repair mechanisms fail?
A mutation occurs, and cancer can form since mutations are occurring quicker than repair is able to take place. There could also be a defective enzyme
How does photolyase use light energy to repair DNA?
Photolyase works in conjunction with two co-factors. The first co-factor (either deazaflavin or methenyltetrahydrofolate) absorb a photon of light or a specific wavelength (in the blue spectrum) and passes this energy to FADH- which then acts as an electron donor, transferring a single electron to the pyramidine photodimer, and in doing so allows the bond between them to be broken.
Which type of enzyme is involved in excision repair?
For nucleotide excision repair, the enzymes that are involved are excinucleases.For base excision repair, the enzymes involved are DNA glycoslyases
What is the enzyme that connects the okasaki fragments and participates in DNA repair?
DNA Ligase
What is a DNA repair enzyme activated by visible light?
DNA photolyase
When the repair mechanism for DNA fails the result is?
Failure of the DNA repair mechanism can result in cancer, mutation or a defective enzyme.

What can you do to prevent cancer?
My Mum always tells me that Tomatoes can help prevent getting Cancer. Also, If you smoke you must stop as that can cause lung cancer. If you get sunburnt easily make sure you get well covered up and sun cream suited to your skin. Fruits and vegetables contain antioxidants, which help repair our damaged cells. Green, orange and yellow fruits and vegetables are your best bet to help prevent cancer. Studies also show that dark fruits, like blueberries and grapes, may also have anti-cancer properties. Also reduce the amount of Red meat in your Diet. A simple answer: You can keep a healthy lifestyle and be self aware.
Is there a connection between cancer and repair of the large intestine?
yes
What results in the decrease in tissue repair neoplasm or invasion or cancer or infection?
Infection results in a decrease in tissue repair.
What type of biology do DNA ligase belong to?
DNA ligase is a very specific enzyme used in microbiology. The enzyme is used to help join DNA strands together and is used for DNA replication and repair.
How many base pairs are still improperly matched after the DNA enzyme-repair complex has completed its functions and repairs?
None.
What are the goals of laceration repair?
The four goals of laceration repair are to stop bleeding, prevent infection, preserve function, and restore appearance.
