Explain one other method (besides electrophoresis) that could be used to purify proteins and compare it to Nickel IMAC?

P.S. Need to explain one method to separate and purify proteins but not electrophoresis, as we have done that in class.

axis of drosophila.

D. What are the role of chordamesoderm in patterning the axes of frog and

fish embryos.

A. sketch the fate maps at blastula stage for snails, sea urchins,

tunicates, zebrafish and xenopus.

B. Sketch drosophila development from single cell through

gastrulation.

C. Sketch xenopus development from single cell through

gastrulation

Bacterial Quorum Sensing, Pathogenicity Islands, and Secretion Systems

1.bacterial quorum sensing may play a role in pathogenicity by:

a) Promoting initial colonization of a new host;

b) Enabling the bacterium to persist within that host; and

c) Allowing some of the bacteria to spread to a new location within a host or to a new host.

Question: Briefly describe how the ability to produce a type 3 secretion system might play a role in a pathogen colonizing the body and causing an infection.

The pathogen can be a bacteria, fungus, protozoa, or virus. In addition to the article, information to include in the paper should include, morphology, gram stain characteristics, virulence factors, susceptibility to antibiotics, host cells, nutritional needs, growth conditions, mechanisms used to evade the immune system and invasion into the host(s), interactions with the hosts and diseases caused and affected body systems. Additionally, students should explain symptoms when the pathogen infects a host, as well as a diagnosis and the therapeutic intervention needed after infection. You may also add information on statistics related to infection (epidemiology) and any new research findings related to the pathogen.

Tumors (and cancer cells) are cells that replicate uncontrollably. Why would it benefit a provirus to convert a normal animal cell into a tumor cell?

Stomata begin to open with the first light of the day. If the water potential in the leaf drops to -0.4 MPa, what will the guard cell's water potential to be during the opening of the stomata?

Lipase is a versatile industrial enzyme that can be applied to various industries. It is one of the most important classes of hydrolytic enzymes that catalyze the hydrolysis of triacylglycerol to diacylglycerol, fatty acids and glycerol. You are a bioprocess engineer assigned by your superior to work with a biotechnologist to provide a proposal on the upstream and downstream processing of microbial lipase targeted to the biodiesel processing application. To begin the project, you are required to present a preliminary investigation report on the following. a. Select a suitable microorganism and a lipid carbon source that can be applied to produce microbial lipase for the targeted application economically at industrial scale with justifications.

I have found a microorganism which can produce Microbial Lipase for biodiesel process application economically at industrial scale by doing research. I found out an article of microorganism name 'Streptomyces sp CS 326'.

The heading of the article says 'A neutral lipase applicable in biodiesel production from a newly isolated Streptomyces sp CS 326.'

what is meant by 'neutral lipase'? Is it different from Microbial lipase? And can i use this microorganism 'Streptomyces sp CS 326' for the production of Microbial lipase for biodiesel process application?

1. What is an animal? List characteristics describing animals.

2. What is the Cambrian Explosion?

3. Is the kingdom “Animalia” monophyletic or polyphyletic?

After visiting a dairy farm one summer afternoon in Utah, three members of a family develop fever, abdominal cramping and diarrhea with blood for 3 days. All three patients reported to their doctor that their symptoms developed the day after visiting the dairy farm where they sampled raw milk. Two of the patients (85 year old female and 18 year old male) became severely dehydrated and required hospitalization. The female patient died 1 week later of multisystem organ failure, related, in part, to gastroenteritis and underlying medical conditions that she had. The second patient was given IV fluids and antibiotics which resolved his symptoms after 1 week. Based on the information provided in this case study, answer the following questions.

1. What organism is the most likely etiologic agent that caused the infection in this family?

2. How was the disease acquired? Explain your answer.

3. Describe how this bacterium causes a more severe disease in immunocompromised individuals.

4. Describe the virulence factors associated with this bacteria.

Ways in which Chemical Control Agents May Affect Bacteria

1. Describe one way an antibiotic can inhibit peptidoglycan synthesis, state how that ultimately kills the bacterium, and give an example of such an antibiotic.

2. Describe one way an antibiotic can alter bacterial ribosomes, state how that ultimately inhibits or kills the bacterium, and give an example of such an antibiotic.

3. Describe one way an antibiotic can interfere with bacterial DNA synthesis, state how that ultimately kills the bacterium, and give an example of such an antibiotic.
