How does mhc class 1 present antigen. Give detailed descriptive answer of what happens within the antigen presenting cell

Can you tell me about DNA extraction. Everything you know, what is the purpose and applications of it, what are the advantages and disadvantages. And please write the function of each chemical:

• RBC lysis buffer
• PBS
• Trizol

Thank you in advance! I am forever grateful for your help.

what is a synopsis that includes a type of dynamic or static stretch and why is this a beneficial stretch?

The molecular weight of methylene blue is 320 g/mol. The concentration of the original sample was 0.005 mg/ml in 10 ml. Determine the molarity (M) of your original sample and each dilution.

Original:
Dilution 1 (1:2 add 3mL of methylene blue + 3mL of water) :
Dilution 2 (1:4 use 3mL of of 1:2 solution + 3mL of water) :
Dilution 3 (1:8 use 3mL of 1:4 solution + 3 mL of water) :
Dilution 4 (1:10 use 0.5 ml of the original methylene blue + 4.5 mL of water) :

Please show all work!!

Directional selection acting upon a favored recessive allele:

a) fixates quickly because heterozygotes do hold an advantage

b) fixates quickly because heterozygotes don't hold an advantage

c) takes time to fixate because heterozygotes do hold an advantage

d) takes time to fixate because heterozgotes don't hold an advantage

e) none of the above

In lab this semester, we have examined several cellular molecules and activities including, but not limited to, cyclosis in Elodea, Protein concentration in various food sources, bovine serum albumin and the relationship between protein concentration and absorbance, Betacyanin and membrane permeability, B-galactosidase and enzyme function, yeast cell growth, and RNA production in cells.

Describe how one of more of the databases/programs utilized in this lab exercise (pBLAST, PDB, DeepLoc, KEGG) could be used to gain information about one of these processes or molecules. Be specific and explain your answer.

Contrast how the activity of the liver enzyme is altered in the following physiological states: (1) After a heavy meal. (2) After you have run half a mile. (3) After you have not eaten for 3 days. Does the activity of the muscle phosphorylase differ under these conditions?

1. Draw a cell with three chromosomes as it moves through mitosis and cytokinesis.

2. Draw a cell with three chromosomes as it move through meiosis and cytokinesis.

3. Why are some cancers heritable and some are not? What is an example of a type of cancer that might be inherited and an example of one that is not?

5. Describe how chemotherapy, radiation, and immunotherapy are used to treat cancer. Describe how cancer cells look and act different than normal cells

6. Describe at least 3 different ways that meiosis and sexual reproduction increases genetic variability in offspring. What advantage does that give sexually reproducing organisms over asexually reproducing organisms? When is asexual reproduction an advantage over sexual reproduction?

7. Choose a genetic disease/disorder and explain its symptoms and its pattern of inheritance.

8. Describe how an adaptation can become common in a population over time. What conditions must be necessary in order for that to happen? What is the mechanism for that to happen?

9. Describe the similarities and differences between artificial selection and natural selection. Give 2 examples of each.

5. Glycolysis

a. The hydroxyl group on the sixth carbon on a glucose molecule is radiolabeled using O18. Please draw out the pathway showing where this radiolabel is in each step of the pathway.

b. In glycolysis, ATP molecules are produced. Please write out the reactions that utilize ATP as well as the ones that create ATP, and explain how many molecules of ATP are made in glycolysis.

c. A reaction is set up with 3-phosphoglycerate, where the phosphate atom is radiolabeled (P32) and incubated with phosphoglycerate mutase (unphosphorylated). Please draw the mechanism, and list the components of the reaction that may be radiolabeled after five minutes.
