Why is a drug that inhibits telomerase not a good choice for cancer therapy? Make sure to explain what telomerase does in a normal healthy cell.

Down Syndrome can be caused by trisomy 21 or by a Robertsonian translocation. Explain specifically how each of these mutations can happen in the cell, and why both cause the symptoms of Down Syndrome.

QUESTION 23

1. What is a technology that improves the safety and extends the shelf life of foods by reducing or eliminating microorganisms?

QUESTION 24

1. Fill in the blank with 2 words.

   [A] (i.e., paying attention to our food, on purpose, moment by moment, without judgment) is an approach to food that focuses on individuals’ sensual awareness of the food and their experience of the food. It has little to do with calories, carbohydrates, fat, or protein. The purpose of [A] is not to lose weight, although it is highly likely that those who adopt this style of eating will lose weight. The intention is to help individuals savor the moment and the food and encourage their full presence for the eating experience.

in your own words please.

What is the role of cytokine signaling in both types of immune responses? In Trypanosoma cruzi infections, innate and adaptive immune responses occur. Which stages of infection in T. cruzi are responsible for stimulating innate, cell- mediated and humoral immunity? Be specific.

What happens to plant cells when placed in a hypertonic solution?

What happens to plant cells when placed in a hypotonic solution?

What is the purpose of Koehler illumination?

Chemotherapy is a commonly used treatment modality for cancer patients. One’s hope is that the treatment will kill the cancer and not kill the patient! Why do we see so many side effects from chemo involving the skin, digestive system and bone marrow?

Select one:

a. Because those are the parts of the body most commonly affected by cancer, so the treatment is concentrated there

b. Because chemotherapy agents make patients more prone to sun damage and spicy or acidic foods

c. Because chemotherapy burns exposed tissues just like radiation

d. Because chemotherapy attacks rapidly dividing cells

Ribosomes can normally be found in all of the following eukaryotic cell locations except:

A. the outer nuclear membrane

B. the rough endoplasmic reticulum

C. the mitochondrion

D. the inner nuclear membrane

E. the chloroplast

What structure in the nuclear envelope of eukaryotic cells allows most proteins to cross, from the cytoplasm into the nucleoplasm, without being unfolded and refolded by chaperones?

A. the smooth endoplasmic reticulum

B. the Golgi apparatus

C. the rough endoplasmic reticulum

D. the nucleoli

E. the nuclear pores

Which eukaryotic structure is normally the last one to make modifications to a polypeptide (like glycosylation of a protein), before it is secreted from the cell?

A. the trans face of the Golgi apparatus

B. the smooth endoplasmic reticulum

C. the cis face of the Golgi apparatus

D. the rough endoplasmic reticulum

E. the nuclear envelope

A thermosensor protein that has been identified was TlpA, a protein in Salmonella that was needed to induce virulence genes at high temperature. Why might a bacteria want to have virulence gene expression coupled to temperature?

Endospores. What are endospores?

When do bacteria make spores?

Briefly describe their structure and formation.

“Organization of Lipids in the Tear Film: A Molecular- Level View” Article.

Identify a specific type of dry eye syndrome. What do the researchers believe are the causes of the condition?

Identify the main objective and aim of the researchers who wrote this article.

What is a tear film? How is it useful to the eye and what are some common ailments associated with film instabilities?

In the article, simulations were performed at different lateral compressions to reflect varying surface pressure conditions expected during an eye blink. Describe the two different behaviors the authors observed when varying the lateral compression.

What evidence allowed the authors to predict glycerine-trioleate’s (TG) position at the surface of the lipid film?

What are micelles and how they are formed?

What do the authors suggest contribute to the stabilization of the tear film during eye blinks?

Describe the results obtained from Figure 7.
