Chapter 17, Problem 4U
FISH analysis of a breast tumor biopsy for HER2 gene reveals two spots of fluorescence in cells. What conclusion do these data support about the tumor?
a. It is likely to contain high levels of the HER2 mRNA.
b. It is likely to contain high levels of the HER2 protein.
c. The HER2 gene is amplified, and treatments targeting the HER2 protein may not be suitable.
d. The HER2 gene is not amplified, and so particular treatments targeting the HER2 protein may not be suitable.

- You are studying pancreatic cancer have matched samples of tumor and healthy pancreatic tissue. You use a microarray to determine gene expression differences between these two sample. You label the healthy tissue cDNA with red fluorescnce and the tumor cDNA with green. You apply these cDNAs to your chip. Beta-actin is a housekeeping gene required for cell structure. What color would you expect the spot for this gene to be? a. Red b. Green c. Yellow d. No color e. None of the abovearrow_forward1). Tumor suppressor proteins monitor DNA and detect damage. Some cancers evade this detection by removing tumor suppressor proteins from the nucleus. An overproduction of what transport molecule could cause this? What is one example of how this overproduction might be targeted for cancer treatment (suggest a hypothetical treatment that would prevent the cancer)? 2) :) Based on the course content thus far, would mRNA vaccines pose a risk to the genomic DNA in a cell? Explain.arrow_forward1a) Why is it possible for you to study the eye colour gene by extracting cheek cells? a. Because the nucleus of every cell in the human body contains the same genetic information. b. Because the cheek cells are located near the cells of the eye and so they are able to exchange DNA. c. Because all genes in the human body are expressed at all times so it is easy to study them. d. All of the above are possible explanations. 1b) What is the purpose of heating the sample to 75°C following addition of the 0.2M NaOH solution? a. To denature the histone proteins that are keeping the DNA tightly coiled. b. To ensure that all the DNA is removed from the swab in preparation for PCR. c. To breakdown the cheek cell membrane to release the DNA from the cell. d. It breaks down the circular DNA down into linear fragments so that they will be easier to visualize.iarrow_forward
- In the experiment below, mice were treated with a virus that inhibited expression of angiopoietin 2, MMP3 and MMP10 in the lung or with a control virus (Mock). Breast cancer cells that express the gene luciferase were then injected into the mammary glands of the mice. The metstasis of the tumors to the lungs could then be measured by imaging the presence of luciferase in the lungs. In 5-6 sentences, explain the data below and why knockout of Angpt2, MMP3 and MMP10 appears to inhibit metstastasis.arrow_forwardUnusually high levels of Mdr1 provide stem cells with a. Nutrients needed b. Protection of their genomes from mutagenic agents c. Apoptotic factors d. Ability to differentiatearrow_forwardHow can Cas9 technology be used in gene therapy. A.

- The figure below summarizes the results of an experiment evaluating the role of Ku80 gene DNA repair. The Ku80 Knock Out mice were generated by genetically deleting the Ku80 gene and the effects of ionizing radiation on lifespan were evaluated. Briefly explain why Ku80 deletion has the observed effects. What form of DNA damage is causing the reduced lifespan and which repair mechanism appears to be responsible for repair of these lesion in normal mice?arrow_forwardIdentification and quantification of expressed genes initially requires a. reverse transcription of mRNA to cDNA b. fragmentation of the whole genome c. ligation to adapters of known sequences d. ligation of a target gene to a vectorarrow_forwardAfter the initial Actualization of the Cit+ phenotype, there was another alteration to the A-3 genome that resulted in increased growth (e.g. Refinement). What explained the increase in growth rate in response to Refinement? A. Increase number of transporters localized to the plasma membrane. B. Increased ability to metabolize glucose. C. Increased citric acid cycle activity. D. Altered promoter activity resulting in constitutive gene expression.arrow_forward

What is the current consensus as the function of p53 and what evidence caused this change in view? b. How does the effect of mutation in the p53 gene differ from the effect of mutation in the RB gene what is the molecular basis for this difference ?arrow_forwardFrom gene expression studies on cancer, you discovered a hypothetical gene called ABCG2 that is overexpressed in human cancer cells. You want to know if this gene is required for cancer cells to survive, but from your efforts at making a traditional gene knock out, you have found that it is required for embryonic development and can't get to the point of doing a cancer experiment. a. How can you redesign the knockout to get past embryonic lethality? b.
