Yes No.Nonscience majors often do not respond to traditional lecture-only biology courses. However, these students still need exposure to basic biological concepts. To accomplish this goal, forensic science was paired with compatible cell biology subjects. Several topics such as human development and molecular biology were found to fulfill this purpose.

Another goal was to maximize the hands-on experience of the nonscience major students. This objective was fulfilled by specific activities such as fingerprinting and DNA typing. One particularly effective teaching tool was a mock murder mystery complete with a Grand Jury trial. Another objective was to improve students' attitudes toward science. This was successful in that students felt more confident in their own scientific abilities after taking the course.

All four statements showed a positive shift after the course p values ranging from. The emphasis on experiential pedagogy was also shown to increase critical thinking skills. Designing successful science courses for nonscience majors can be a challenge. For example, nonscience majors often have negative attitudes toward science French and Russell, Experiential learning has been shown to overcome this obstacle French and Russell, However, it can be problematic to design hands-on exercises that are readily done by nonscience majors yet are sophisticated enough to sustain inquiry-based learning and enhance critical thinking.

I wished to design a course that would address these challenges and would incorporate cell biology. To that end, I developed a forensic science course that incorporated these three goals: enhance critical thinking, improve attitudes toward science, and introduce cellular biology concepts.

To accomplish these objectives, forensic science has many advantages. For example, it readily lends itself to interactive pedagogies such as inquiry-based learning, cooperative learning, and problem-based learning, all of which enhance critical thinking Lawson et al.

Forensics is also an umbrella under which almost any scientific subject can be taught Reddy, ; Zeno, Finally, students, including nonscience majors, learn more when the topic interests them Project Kaleidoscope, Forensics fits this very well because it has an enduring appeal that predates the current frenzy of popular television shows and will likely outlive them.

Recently, forensics courses have spilled out across the academic landscape Forensic Science in the News, The course described here is different because the forensic science is paired with cell biology topics such as human development, enzymology, and molecular biology. Because of forensics' popularity, educational supply companies have created several forensic kits and materials Carolina Biological, ; Wards, These kits are appropriate for middle school through college and I have used them successfully for nonscience majors at the college level.

In some cases, I purchase individual reagents or use commonly available supplies rather than kits. These are used with PCR reagents already available in the lab. The pen ink chromatography uses Whatman No. The sample pens were purchased from an office supply store. This store was also where I purchased blood spatter materials—large rolls of white paper, red tempura paint, tape measures, calculators, and protractors.

Individuals with certain inherited characteristics are more likely to obtain mates than other individuals. Mate Choice. According to current evolutionary theory, which of the following is true?

Populations are the units of evolution. This is the basis of the modern synthesis of evolution. Gene Pool. Genetic Drift. Unpredictable fluctuations in allele frequencies from one generation to the next because of a population's finite size.

Gene Flow. Genetic additions to or substractions from a population resulting from the movement of fertile individuals or gametes. A change in the DNA of a gene, ultimately creating genetic diversity. Natural Selection.

Differential success in the reproduction of different phenotypes resulting from the interaction of organisms with their environment. Evolution occurs when natural selection causes changes in relative frequencies of alleles in the gene pool. Having two identical alleles for a given gene. Having two different alleles for a given gene.

Pedigree Analysis

Dominant allele. An allele that is fully expressed in the phenotype of a heterozygote. Recessive allele. An allele whose phenotypic effect is not observed in a heterozygote. Versions of genes. Allelic frequencies change in:. Allelic frequencies change within a population. How many alleles do you inherit for each genetric trait?It's what makes you unique. Unless you have an identical twin, your DNA is different from that of every other person in the world.

And that's what makes DNA fingerprinting possible. Experts can use DNA fingerprints for everything from determining a biological mother or father to identifying the suspect of a crime. What, then, is a DNA fingerprint and how is it made? Here, you'll find out by solving a mystery—a crime of sorts. First, you'll create a DNA fingerprint we'll supply the lab and all necessary materials. Then you'll compare this DNA fingerprint to those of all seven suspects to nab the perpetrator.

Let's get to work!

Assemble a virtual DNA fingerprint and use it to identify the culprit in a hypothetical crime. In the last 15 years, DNA has played an increasingly important role in our legal system. Tissue evidence is now routinely collected during criminal investigations in hopes that it will provide genetic clues linking suspected criminals to crimes.

DNA profiles help forensic investigators determine whether two tissue samples -- one from the crime scene and one from a suspect -- came from the same individual. Fortunately, the genetic comparison doesn't require that investigators look at all of the DNA found in the tissue samples.

That would take months or even years.

DNA Profiling in Modern Medical Forensic (With Diagram)

Instead, by marking a small number of segments of DNA in one sample and then checking for the presence or absence of those segments in the other sample, investigators can say with some assurance whether the samples are from the same person.

How do they do it? Investigators use chemicals to cut the long strands of DNA into much smaller segments. Each segment has a specific length, but all of them share the same repeating sequence of bases or nucleotides. The DNA segments used in forensic investigations are, of course, much longer than this. Investigators use a process called gel electrophoresis to separate these repeating segments according to length. Next, they introduce a small set of radioactive "markers" to the sample.

These markers are segments of DNA of known length, with bases that complement the code of, and bind to, sample segments of the same length. Markers that do not bind to sample segments are then rinsed away, leaving in place only those markers that bound to complementary sample segments.

Photographic film, which darkens when exposed to the radioactive markers, identifies the location of all marked sample segments.

This film, then, becomes the DNA "fingerprint" that forensic investigators analyze. The final step is a relatively simple matter of lining up the sample profiles side by side and comparing them for the presence or absence of segments with particular lengths.

The more segments the two samples have in common, the more likely it is that the samples came from the same person.
