A) Deoxyribose- the purple pentagon
B) phosphate - the blue circle
C) nitrogenous base - the blue rectangles in the middle that are connected
Explanation:
<span>Lafora disease is the most severe teenage-onset progressive epilepsy, a unique form of glycogenosis with perikaryal accumulation of an abnormal form of glycogen, and a neurodegenerative disorder exhibiting an unusual generalized organellar disintegration. The disease is caused by mutations of the EPM2A gene, which encodes two isoforms of the laforin protein tyrosine phosphatase, having alternate carboxyl termini, one localized in the cytoplasm (endoplasmic reticulum) and the other in the nucleus. To date, all documented disease mutations, including the knockout mouse model deletion, have been in the segment of the protein common to both isoforms. It is therefore not known whether dysfunction of the cytoplasmic, nuclear, or both isoforms leads to the disease. In the present work, we identify six novel mutations, one of which, c.950insT (Q319fs), is the first mutation specific to the cytoplasmic laforin isoform, implicating this isoform in disease pathogenesis. To confirm this mutation's deleterious effect on laforin, we studied the resultant protein's subcellular localization and function and show a drastic reduction in its phosphatase activity, despite maintenance of its location at the endoplasmic reticulum.

Answer:
Carbon, hydrogen, and oxygen. (Ans. C).
Explanation:
Carbohydrates are defined as macronutrients consisting carbon, hydrogen, and oxygen atoms, which are found in vegetables, fruits, milk products, and grains. They are known as the basic food group, a healthy diet, and playing important role in the proper body functioning. Some important function of carbohydrates are:
1) Carbohydrates provide energy for working muscle, and fuel for the central nervous system.
2) Carbohydrate are also important for brain function.
3) They help to reduce the risk of diseases.
4) In the form of fiber carbohydrates helps to improve the health of digestive system.
Answer:
C
Explanation:
In the human body, the parasites multiply in the liver, and then infect red blood cells. The most common symptoms of malaria including fever, are caused when the parasites invade red blood cells (erythrocytes) and rupture.
I'd say it's an example of genetic drift.
Characteristics:
• Common in small populations.
• Alleles start being more frequent over time
