Indicate whether each of the following statements is true of depurination (DP), deamination (DA), or pyrimidine dimer formation (DF). A given statement may be true of any, all, or none of these processes. This process is caused by spontaneous hydrolysis of a glycosidic bond. This process is induced by ultraviolet light. This can happen to guanine but not to cytosine. This can happen to thymine but not to adenine. This can happen to thymine but not to cytosine. Repair involves a DNA glycosylase. Repair involves an endonuclease. Repair involves DNA ligase. Repair depends on the existence of separate copies of the genetic information in the two strands of the double helix. Repair depends on cleavage of both strands of the double helix.
Answer:
- This process is caused by spontaneous hydrolysis of a glycosidic bond: depurination and deamination
- This process is induced by ultraviolet light: pyrimidine dimer formation
- This can happen to guanine but not to cytosine: depurination
- This can happen to thymine but not to adenine: pyrimidine dimer formation
- This can happen to thymine but not to cytosine: none
- Repair involves a DNA glycosylase: deamination
- Repair involves an endonuclease: depurination, deamination and pyrimidine dimer formation
- Repair involves DNA ligase: depurination, deamination and pyrimidine dimer formation
- Repair depends on the existence of separate copies of the genetic information in the two strands of the double helix: depurination, deamination and pyrimidine dimer formation
- Repair depends on cleavage of both strands of the double helix: none
Explanation:
Depurination is the loss of purine bases (either adenine or guanine), while deamination refers to the removal of an amino group. During depurination, a β-N-glycosidic bond is cleaved by hydrolysis and a nucleic base is released (either adenine or guanine). All DNA bases may undergo deamination, except thymine (since thymine does not have an amino group). The ultraviolet (UV) radiation can cause thymine or cytosine to form dimers (e.g., pyrimidine dimers), being thymine dimers the most common lesion when DNA is exposed to UV light. Pyrimidine dimers may be repaired by different excision mechanisms, e.g., nucleotide excision repair, where the recognition of the DNA damage leads to the removal of the DNA fragment containing the lesion. DNA glycosylases are enzymes involved in the mechanism of base excision, these enzymes recognize and remove damaged bases by hydrolysis of the glycosidic bond, producing an abasic (apurinic and apyrimidinic) site. A DNA ligase enzyme covalently joins two DNA molecules by forming a phosphodiester bond, which is required during these processes.
*Earth Science* Active continental margins where the plate boundary is ocean-continent convergent are characterized by accretionary wedges.
True or false?
The correct answer is True
Explanation
An accretion wedge is an area where deformed sediment accumulates that occurs at a convergent edge at the boundaries of subduction plates (ocean-continent). This process occurs when sediments from the oceanic crust accumulate to the block of continental crust produced. by the subduction movement of the oceanic crust. So, the correct answer is True.
For each - choose either peroxisome or lysosome, both or neither Group of answer choices uses hydrolases lysosome uses the enzyme catalase peroxisome is one of the main sites of fatty acid breakdown peroxisome combines with endosomes to digest ingested matter lysosome capable of converting hydrogen peroxide to water and oxygen peroxisome destroys engulfed bacteria both lysosome and peroxisome main role is metabolism both lysosome and peroxisome digestive interior is acidic lysosome proteins are derived from the endoplasmic reticulum
Answer:
Uses hydrolases -lysosome
Uses the enzyme catalase- peroxisome
Is one of the main sites of fatty acid breakdown- peroxisome
Combines with endosomes to digest ingested matter- lysosome
Capable of converting hydrogen peroxide to water and oxygen- peroxisome
Destroys engulfed bacteria- lysosome
Main role is metabolism- both lysosome and peroxisome
Digestive interior is acidic- lysosome
Proteins are derived from the endoplasmic reticulum- Peroxisome
Explanation:
The lysosome is a membrane-bound organelle found within a cell whose main function is to ensure the break down of biological polymers, such as proteins and polysaccharides. It is comprised of enzymes that are degradative in nature that can degrade biological polymers such as proteins, nucleic acids, lipids, etc. They contain various types of hydrolytic enzymes such as proteases, nucleases, glycosidases, lipases, phospholipases, phosphatases, and sulfatase. These enzymes are acid hydrolases as they function in the acidic environment of the lysosome. Lysosomes are also used by the cell to destroy invading viruses and bacteria.
Peroxisomes are membrane-bound organelles found within the cytoplasm of a cell. They are derived from the edoplasmic reticulum. Peroxisomes are involved in lipid biosynthesis, for example, cholesterol and dolichol are synthesized in peroxisomes. Peroxisomes are also involved in the synthesis of bile acids from cholesterol.
Peroxisomes contain enzymes that oxidize fatty acids and amino acids. Peroxisomes also contain enzymes such as catalase that convert hydrogen peroxide to water and oxygen preventing oxidative damage by these reactive oxygen species.

The esophagus is a bony tube.
The esophagus is a muscular tube.
The esophagus moves food from the mouth to the small intestine.
The esophagus moves food from the mouth to the stomach.
Which of the following statements are true about the esophagus?
The statements that are true about the esophagus are:
The esophagus is a muscular tube.The esophagus is the muscular tube of the digestive tract that develops from the pharynx to the stomach.
The esophagus moves food from the mouth to the stomach.This part of the digestive system is traversed by food, which enters through the mouth, passes through the pharynx, crosses the esophagus and reaches the stomach.
In this process, the esophagus has an active participation, since its walls contract to promote the advance of the food.
Therefore, we can conclude that the esophagus is a muscular tube that moves food from the mouth to the stomach.

Answer:
Certain plants contain compounds similar to ecdysone which serve as a defense against insects. False
Juvenile hormone levels are high in insect larvae, but must decrease in order for metamorphosis to occur. True.
Chemicals similar to ecdysone and juvenile hormone are widely used commercially to control insect pests. True
Explanation:
The plants produce toxic chemicals such as terpenoids, alkaloids, anthocyanins, phenols, and quinones as a defense against insects. Juvenile hormone levels are high in insect larvae but its concentration decrease when the insect transform into adult stage and in order to occur metamorphosis. Ecdysone and juvenile hormone are widely used as insecticide because it prevents the insects to transform from larva to adult so if they can't mature they can't harm the plants or other things of our environment.
