1) What is BLAST? What does it do? What is in a BLAST "result"? What is an "alignment" in the case of BLAST?

2) There is always a symbol indicating a relationship between each pairwise amino acid in the query and subject; what do the different symbols mean?

"+" vs "-" vs " " vs "<a specific letter matching letter>"

5. Draw a diagram with the following components :

a.) mRNA with 15 nucleotides (indicate the sequence); label 5’ and 3’ ends.
b.) small and large ribosomal subunits (show the tRNA binding sites and label them A,P,E)
c.) tRNA carrying an amino acid that corresponds to the codon being read by the ribosome

“Protein A” is phosphorylated at one amino acid by a kinase, “protein B”, and dephosphorylated by a phosphatase, “protein C”.

You have purified all three of these proteins and want to determine the structural changes that occur when protein A is phosphorylated or dephosphorylated. Explain in detail how you would go about designing and conducting this investigation.

Sickle cell anemia is a genetic disease resulting from a single amino acid substitution in the hemoglobin β chain. This mutation causes hemoglobin to polymerize into strands in the deoxygenated state, leading to the erythrocytes forming a sickled shape. Why does the mutation lead to polymerization and why does this only occur in the deoxygenated state?

Human Resource professionals has certain set of skills, give at least five (5) essential human resource management skills needed to run a successful human resource department and explain how these skills are used. Provide an examples.

How is fat digested and absorbed after eating a peanut and jelly sandwich on whole wheat including the constituents representing fat and how and where they are digested and absorbed and how and where fat is utilized or stored in the body. Include the chemical, hormonal, and enzyme changes that impact the proper environment of this meal.

5. Give an example each of a glycerophospholipid and a glycolipid. What are the products of their complete hydrolysis? Show on a hand-drawn diagram the action of each hydrolytic enzyme to release the products you mentioned?       

Diagram of positions acted upon by the hydrolytic enzymes:

A mutation in the liver enzyme PFK-2/FBPase-2 results in the loss of cAMP-dependent kinase phosphorylation site, thus resulting in a loss of responsiveness to cAMP-dependent kinase. What are the effects of this mutation on blood glucose levels during times of fasting? Please explain your answer.

Describe the flow of foodstuff through the digestive tract starting with ingestion at the buccal cavity and end with defecation at anus. For each region state (1) which enzymes are secreted if any, (2) what the substrates of that enzyme would be in that region, and (3) what the products of chemical digestion would be in that region.
