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
Answer:
New cells take the place of old or damaged cells as they die. Cancer disrupts this process and leads to abnormal growth in cells. It's caused by changes or mutations in DNA. DNA exists in the individual genes of every cell.

Climax-Pattern Theory
<h3><u>Explanation;</u></h3>
- The Climax Pattern Theory emphasizes that a natural community is adapted to the whole pattern of environmental factors in which it exists.
- In addition to climatic factors, e.g. wind, there are a whole range of edaphic factors, fire, and biotic factors, including grazing, disease and mutualistic and competitive interactions.
- The Climax Pattern Theory allows a continuity of climax types, varying gradually along environmental gradients and not neatly packaged into discrete climax types.
Answer:
Eukaryote cells have a membrane-bound nucleus and prokaryotic cells do not
Explanation:
Answer:
I think the answer is a plant cell contains one large vacuole in its wrong because they have a nucleus I did not all plants have the same size or shape and they only have one large vacuole or sap vacoule hope it helps
