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:
Soils in warmer or wetter climates are more developed than soils in cooler or drier climates. ... Soils that are more developed have more horizons and deeper horizons than soils that are less developed. Wet conditions favor leaching, or moving deeper with water, of clay and other minerals so that E and B horizons develop.
D. Prokaryots do not have any genetic material.
The right answer is the option a, part of a binary system<span>. A binary system is two astronomical bodies which orbit one around each other due to the gravitational atraction that they mutually exert on each other. . On the other hand, Sun is a yellow star, a main sequence star and of average absolute magnitude. </span>
Competition is one of the many types relationships in the ecosystem. It is an oppositional relationship because unlike in symbiotic relationships, the organisms do not peacefully coexist. Using the given information above, we can deduce that the two fungi compete with one another in terms of the resources plus the habitat.
