Which technique would you use to analyze and compare gene
expression between normal cells and cancer cells to identify
differences in mRNA expression between these cell types? Explain
each steps reasoning.
Explain the regulation of gene expression in eukaryotic
cells.
Discuss mechanisms by which gene expression may be
altered.
How do these alterations induce cancer-causing mutations in
cell DNA?
Explain how cancer is formed.
Describe genetic changes found in cancer cells and how these
changes lead to alterations in cell behavior.
Determine whether proteome data can be utilized in genetic
disorder diagnosis.
Relate the Human Genome Project data to the analysis of cancer
genes.
You design a microarray experiment to determine the difference
in gene expression patterns between normal and cancerous lung
tissue from humans. You label the cDNA derived from a lung tumor
with a red fluorescent dye and the cDNA derived from normal lung
tissue with a green fluorescent dye. You hybridize the cDNA to a
microarray chip in which each spot corresponds to a DNA sequence
from a different human gene.
a. What can you infer about a particular gene’s expression...
Cell Cancer:
a. In what ways are cancer cells different from normal
cells in terms of properties and behavior?
b. What is the difference between an oncogene and a
tumor suppressor gene?
Which technique would you use to determine the following? You
can only use each technique once. Not all
techniques will be used. Explain your answer.
techniques available:
- SDS-PAGE and Western blot
- TLC
- freeze-fracture
- lactoperoxidase labeling
- FRAP/photobleaching
- photoactivation
- hydropathy plot
1. You want to determine if a membrane has proteins in it or
not.
2. You want to determine if a cell membrane has the Na+/K+
transporter.
3. You want to determine the types...
Compare and contrast regulation of gene expression with use of
an enzyme inhibitor. List one advantage and disadvantage for
regulating gene expression and one advantage and one disadvantage
for using inhibitor.
Which of the following systems would you use for the expression
of an antibody? Explain you decision, why you would or would not
use:
a. CHO
b. PERC.6 (human cell line)
c. Saccharomyces cerevisiae (yeast)
d. E.coli
e. Transgenic plant
Which of the following is a difference between prokaryotic and
eukaryotic gene expression
Group of answer choices

holoenzyme
2)Eukaryotes produce an immature mRNA
3)Trancription and translation can occur simultaneously in
Prok.
4)Eukaryotics have more diverse promoters
5)All of the above
