2. Who are the stakeholders of Health Information Technology(HIT)? Explain how each person utilizes HIT and how do they benefit.
3. What gave rise to various types of informatics disciplines? Which informatics discipline would you be more interested in from the options available in Chapter 1? Briefly discuss your reason.
Assume a drug slows down the processes of DNA replication and mitosis in cell culture, but the overall length of the cell cycle for these cells remains the same. Which of the following would be true:
Complete the table below that describes different types of chemical bonds. Bond Name Type of interaction between atoms Sharing of electrons Polar Covalent Bond Equal Sharing of electrons ionic Bond Unequal sharing of electrons results in regions of opposite charge in a molecule. The regions of opposite charge cause these molecules to bond to each other.
The ability of adult humans to digest milk is dependent on the persistence of the enzyme lactase into adulthood. Most humans stop producing lactase after infancy but a small portion of the population retains this ability. Non-persistence of lactase is a Mendelian trait that is autosomal recessive.
Give the genotypes for a mother who is non-persistent and a father who is heterozygous and lactase persistent.
On a piece of paper, do a Punnett square that predicts the lactase characteristics of the children from these parents then give me the phenotype ratio of the kids.
What are the possible outcomes of staining a smear without heat-fixing it? Discuss the chemical mechanism of Gram’s stain. There are bacteria that cannot be stained by Gram’s stain method of staining. Why? In the process of staining, for example, if you run out of Crystal violet can you use Methylene blue instead? Explain your answer. Discuss the principle of acid-fast staining. What is the importance of finding an acid-fast bacteria in a sputum smear? What reagents are used in performing acid-fast stains using Fluorochrome stain and how is it done?
There is a moth in England called the peppered moth. Before Britain’s industrial revolution, these moths were usually salt and pepper colored. Because of their coloring, they blended in well with the tree trunks on which they tended to rest. The coloring helped them hide from the birds that ate them. During the British industrial revolution, industry expelled a lot of soot from the burning of coal into the environment. This soot darkened the tree trunks, and it was noted that black-colored moths were becoming predominant. The idea is that with soot in the environment, black-colored moths fared better than light-colored moths. There is some debate as to whether this is actually the case or not, but for the sake of this question, let’s assume it is.
Explain the concepts from four observations using the moth as an example.
How does the moth illustrate the first observation, the second observation, etc.?
Suppose you have a human tissue culture line in which both normal copies of the gene coding for the Mad2 protein have been replaced by mutant gene copies, each of which contains the same temperature-sensitive mutation. The resulting mutant Mad2 protein folds and functions normally when the cells are maintained at 22°C, but the protein misfolds and is inactive when the cells are transferred to 37°C. Assume that all of the cells in this line are synchronous (i.e., they all pass through the same stages of the cell cycle in unison). If you shifted the cell population to 37°C sometime in G2, what plausible prediction could you make about the chromosomal makeup of at least some of the daughter cells generated by the subsequent mitoses? Briefly explain the basis of your prediction.
Make an analogy of cell mechanism. correlate how the different cell structures and their respective functions work to maintain the cell function, to an observable system in your surroundings/ community/ society.
reference/example: we can compare Arellano University Legarda to a cell, where the wall of the university is the cell membrane, separating AU from its surroundings.
Illustrate and discuss your analogy (comparison) below. Make sure that all or majority of the cell parts are included.
in a tumor cell line, we isolate gene x which has a single missense mutation compared to the WT gene. You isolate the WT of Genex and call it x-gene x. when we delete gene x from the tumor cells this makes cell division slow, and cells stop growing independent of anchorage. When we delete both copies of x-gene x this causes cells to die. How can we test the relationship between missense mutation and cancer?
1. fuse x- gene x to gfp express it in normal cells and monitor its localization by fluences micro.
2. fuse x-gene x and gene x to GFP, express them in normal cells, and compare their localization patterns
3. show that the missense mutation is sufficient by introducing the identical mutation into x-gene x expressing it in a noncancer cell line and monitoring cancer phenotypes
4. express the protein with the missense mutation purify it and show that it has biochemical activity in a test tube
5. show that the missense mutation is sufficient by converting the codon back to wild type expressing it in a noncancer line and monitoring cancer phenotypes.
