Homework Answers
Alzheimer disease is caused due to protein aggregation of beta-amyloid proteins. Beta-amyloid proteins aggregate and form plaque which disrupt the normal functioning of neurons.
Alpha-synuclein plays a part in Parkinson disease.
aggregation of beta-synuclein leads to neurodegeneration.
Tau protein helps in the cytoskelton of neurons.
So correct answer is option A.

15. You are conducting a bioinformatics analysis on amyloid-beta protein which causes Alzheimer's disease when misfolded. You notice that one position in the alignment is comprised of two different amino acids across sequences. Your query sequence (the one you searched with) has a valine in this position. What is likely to be the other amino acid? (2pts) A) Glutamic acid B) Lysine C) Leucine D) Cystine E) Serine

5. Sickle-cell disease is an interesting genetic disease. Normal homozygous individuals (SS) have normal blood cells that are easily infected with the malarial parasite. Thus, many of these individuals become very ill from the parasite and many die. Individuals homozygous for the sickle-cell trait (ss) have red blood cells that readily collapse when deoxygenated. Although malaria cannot grow in these red blood cells, individuals often die because of the genetic defect. However, individuals with the heterozygous condition (Ss) have some...

10. Protein folding, in most cases, is complex and inhibited by aggregation. Which of the following is false regarding protein folding? A. Chaperones of the heat shock classes do not promote folding, but rather inhibit aggregation. B. Enzymes promote the formation of proper disulfide linkages by eliminating improper folding. C. All proteins require the input of energy and the assistance of chaperones for folding. D. Secondary structures usually form first in folding.

23. A protein called Ras is tethered (linked) to the plasma membranes of stem cells where it participates in signal transduction pathways that affect stem cell proliferation. Which of the following covalent modifications would be responsible for tethering (linking) the Ras to the membrane? A. Phosphorylation B. Glycosylation C. Lipid modification D. Ubiqutiylation E. Acetylation 24. What do transmembrane proteins in the peroxisome, nucleus, and mitochondria all have in common? A. They are all co-translationally inserted into the membrane B....
