how forensic scientists take advantage of genomic variations in
noncoding regions of DNA • the techniques of polymerase chain
reaction (PCR) and gel electrophoresis Introduction: In recent years,
law enforcement has been revolutionized by molecular biology. When
human tissues are left behind at crime scenes, these tissues can be
collected and processed to yield samples of DNA, which can then be
treated to isolate specific DNA fragments that are highly variable in
the human population. Which band pattern among Lanes 3 to 6 seems
to be the closest match to the band pattern in Lane 2, where the crime-
scene DNA fragment was loaded? Which suspect appears to be the
culprit? What is the molecular weight (in base pairs) of the fragment
in Lane 2 (DNA from the crime scene), Lane 3 (Suspect 1), Lane 4
(Suspect 2), Lane 5 (Suspect 3), and Lane 6 (Suspect 4)? Part C How
does analyzing DNA profiles using the gel electrophoresis tool allow
you to draw both qualitative and quantitative conclusions about the
likely identity of the suspect in this case? Judging by the sizes of the
fragments you measured in Part C, about how many repeats of the 16-
base-pair sequence would you expect to find in each of the suspect’s
genomes? In this lab activity, you targeted just one fragment of DNA
to build the DNA profile of each suspect and the crime-scene sample.
Real-world DNA profiles target multiple fragments. What is the
advantage of targeting more than one fragment and having each DNA
profile feature multiple bands?

BIO 240 Disruption of a Marine Food Web Worksheet

Examine the graphs in the Lab Book, and describe any trends you
observe among kelp, purple sea urchin, and sea otter populations.
What happened to all three populations when catastrophe struck the
sea otters? Which populations were wiped out, and in what order?
Why do you think the removal of the otters caused the other two
populations to crash as well? Examine the graphs in the Lab Book.
What happened to the populations’ growth patterns when 100
individuals of each species were reintroduced to the habitat? What
would have happened if you had only reintroduced the kelp and the
urchin? Explain. What if you had only reintroduced five individuals
of each species? Would that have worked to restore the populations?
Explain your hypothesis. Describe the results of the simulation. Was
your hypothesis supported?

BIO 240 Invasive Species Worksheet
==============================================
BIO 240 Introduction to Systematics Worksheet
What three taxa appear in the main window when you first enter the
Systematics Lab Room? At what level of classification are these three
taxa? List one trait for each of these three taxa that distinguishes it
from the others. Which of these organisms are included in Eukarya?
Select all that apply. What groups did you click through to get to
classes Mammalia and Reptilia? Which two of the following species
are more closely related: red-eared slider, vampire bat, American
alligator? What is the common name of the species you have arrived
at? What is the name and level of the taxon where the two species’
lineages diverge?
==============================================
BIO 240 Invasive Species Worksheet
Describe the growth patterns of the mouse, cougar, and red-eared
slider populations when pythons are not present. Describe the growth
of the Burmese python population immediately after they were
introduced. What happened to the populations of the other animals?
Suggest one reason why the introduction of Burmese pythons to this
ecosystem may have caused the effects you observed. What happened
to the cougar and Burmese python populations when 80% of the

Burmese pythons were removed? What do your observations reveal
about the challenges involved in fighting invasive species? Based on
your observations of Burmese python population trends, recommend a
way managers could fight the Burmese python invasion in the
Everglades. Explain your reasoning. Would you recommend
introducing another nonnative species from Southeast Asia that is
known to prey upon the Burmese python or its eggs? Explain. Not all
invasive species are predators. Which of the following characteristics
would help any nonnative species, regardless of its place in the food
chain, become invasive? Select all that apply.
==============================================
BIO 240 The Inheritance of Color Blindness Worksheet
What percentage of Couple 1’s male offspring will be color blind?
What percentage of their female offspring will be color blind? Couple
2 comes into your office. The husband is color blind; the wife is
homozygous for the normal vision allele. Couple 3 comes into your
office. The husband is color blind; the wife is heterozygous for the
color-blindness allele. Review the results you obtained for the female
offspring of the three couples. Based on your results for the female
offspring, predict whether color blindness is a dominant or recessive
trait. Explain your reasoning. Complete the Punnett squares below to
determine the possible genotypes of each couple’s male and female
offspring. (X represents the normal color vision allele. X represents
the color-blindness allele. Y represents the Y chromosome, which
does not carry the color-vision gene.) Review the results you obtained
from the lab for the female offspring of all three couples. Then, look
at the female offspring (the offspring with two X chromosomes) in
your three Punnett squares. What genotype must a female child have
in order to be color blind? Explain why color blindness occurs more
commonly in males than females. Based on your Punnett squares,

determine whether a son can inherit color blindness from his father.
Explain your reasoning.
==============================================
BIO 240 Week 1 Comparing Cell Structures Worksheet
(UOP)
Complete the following charts comparing prokaryotes and eukaryotes,
plant and animal cells, and cells and viruses.
==============================================
BIO 240 Week 1 DQ 1 Cells (UOP)
What are some of the ways cells communicate similar to the ways we
humans communicate with other people or with an organization? How
are they different?
==============================================
BIO 240 Week 1 DQ 2 Virus (UOP)
Would you consider a virus living or non-living? Why? How does this
agree or disagree with classification scheme applied by the scientific
community?
==============================================

BIO 240 Week 1 Photosynthesis and Respiration Paper
(UOP)
Write a 700- to 1,050-word paper summarizing the events of cellular
respiration and photosynthesis and examine the relationship between
the two.
Include the following in your paper:
- For photosynthesis, include a summary of the events in:
- The Light Dependent Reaction
- The Calvin Cycle (Light Independent Reaction)
- For cellular respiration, include a summary of the events in:
- Glycolysis
- Krebs Citric Acid Cycle
- The Electron Transport Chain
- Examine the relationship between photosynthesis and cellular
respiration.
- Write the general formula for photosynthesis.
- Write the general formula for cellular respiration.
Explain the relationship between the two that should be obvious from
the formulas.
==============================================
BIO 240 Week 2 DQ 1 (UOP)
There is a fierce competition among individuals within any species,
humans included, to gain access to reproductive privileges. The
“fittest” – a term that signifies the largest, prettiest, and most sexually
attractive members, succeed in predominantly mating and having
offspring, while the less attractive ones often do not. What is the role
of such sexual selection from an evolutionary standpoint?

Instead of engaging in fights over potential mates, what would be the
problem of simply mating with family members, say, siblings and
other relatives? Isn’t this a more efficient way to spread genes,
without the added peril of having to find potential mates, which could
be a dangerous, strenuous, and uncertain activity? Why not take that
and "run?"
==============================================
Would two identical twins growing up in different neighborhood
grow up differently?
==============================================
BIO 240 Week 3 DNA and Protein Synthesis (UOP)
Answer the following questions, in a total of 500 to 700 words.
- Describe the structure of DNA and the steps of protein synthesis.
- Describe the relationships between the following terms:
- DNA
- Chromatin material
- Gene
- Chromosome
- Use the following gene in protein synthesis:
TAGGACCATTTTAGCCCC
- Show the mRNA.
- Show the tRNA.
- Name the amino acids that will be placed in the polypeptide chain.
(Use the codon table in Ch. 17 of Campbell Biology.)
- A gene will direct the making of polypeptide chains, and

polypeptide chains form proteins. All enzymes are proteins.
Therefore, how would you explain carrying a gene for a trait that does
not show up in the offspring?
- In order for DNA to pass genetic information to the next generation,
DNA must replicate successfully. Mistakes in replication could result
in major problems in heredity.
- Explain how DNA replicates.
- Describe the formation of the leading strand and lagging strand and
include the enzymes involved.
Why do the legs replicate differently?
==============================================
Craig Venter made a new life form (a bacterium) from scratch –
essentially from computer database, and a few bottles of chemicals:

Institute-creates-first-synthetic-life-form
http://www.nytimes.com/2010/05/21/science/21cell.html
If these and other such DNA-based technologies become widely used,
how might they change the way evolution proceeds, as compared with
the natural evolutionary mechanisms of the past almost 4 billion
years?
==============================================
Is there danger of discrimination based on testing for “harmful”
genes? Would you support cloning of life forms? How about a human

clone? What policies can you suggest that would prevent or permit
such practices?
==============================================

==============================================
Consider the human eye, an exquisitely adapted organ that gives rise
to stereo vision in full color (see, for instance, “The Evolution of
Primate Color Vision” by Gerald H. Jacobs and Jeremy Nathans,
Scientific American, April 2009 issue, pp. 56-63).
Explain, strictly from within the framework of Darwinian evolution,
how natural selection “crafted” such an organ.
==============================================
How do you think we could trace back the evolution of organs within
our body by hundreds of millions of years – from our reptile ancestors
– by examining coevolution patterns and fitness landscapes?

Discuss, for instance, the “missing link,” Tiktaalik, that has made
headlines around the world (see “Your Inner Fish” by Neil Shubin).
What kind of selection pressures could have been at work here, based
on species adaptations, climate changes, and shifting landmasses?
==============================================
