Answer: to help in cell division in animals
Explanation:
The correct answer is: 5) NER recognizes helix distortions, while BER recognizes specific base damage.
DNA damage that occurs as a result of radiation, oxidizing reagents, chemicals and other mutagens can be repaired. Excision repair repairs single strand DNA damage and it includes:
• Nucleotide excision repair (NER)-it detects and repairs types of damage that distort the DNA double helix such as those of UV radiation (thymine dimers); not only the damaged nucleotide(s) are removed but also a surrounding patch of DNA
• Base excision repair (BER)-it detects and removes certain types of damaged bases (small, non-helix-distorting bases); enzyme glycosylase is responsible for this type of repair
Some viruses cause infected cells to <u>lyse. </u> Lysis is the dissolving of the cell by factors like viral, enzymic, or osmosis. Lysis in medical term also means a presence of symptoms of complicated or acute diseases. Example of this disease is the tumor lysis syndrome.
