On October 26th, Carleton Comet was at a picnic with some other people. They were having a good time until the sky suddenly darkened and it became pitch black. When the sky lightened again, Carleton Comet was dead from a steak knife. Our job in this project was to figure out who did the murder. The suspects were Fred Flimmer, Nancy Normal, Theresa Terra, Glen Glee, and Sam Sophomore. Some evidence given to us was some blood, a couple pens, a knife with fingerprints, and a strand of hair. We used this evidence to do many precedures which are listed in the key terms section to determine who did the murder.
KEY TERMS:
Chromatography: the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates. We used this to find who used the ink from a pen to write you are a dead man on a piece of paper.
DNA Fingerprinting: a technique which uses the individuality of DNA molecules to distinguish between organisms, or to show the relationships between them. We used DNA found on the crime scene to match up with the suspects.
Pedigree: A family tree that shows if someone has a disease or is a carrier of a disease. We used this to determine if people were related to each other and had diseases.
Karyotype: the number and visual appearance of the chromosomes in the cell nuclei of an organism or species. This was important so that we could figure out if people had a syndrome. Some syndromes create behavioral problems which could cause them to kill somebody.
Hair analysis: We matched up the hair sample to a human hair and there was a match.
Blood analysis: Using the blood found on the crime scene, we gave the blood different antigens to see what type of blood it was to match it to the person with the same blood type.
Antigen: a toxin or other foreign substance that induces an immune response in the body, especially the production of antibodies.
We used these antigens to determine what blood types where found at the crime scene.
Phenotype: the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Homozygous: Alternative forms of a given gene are called alleles, and they can be dominant or recessive. When an individual has two of the same allele, whether dominant or recessive, they are homozygous.
Heterozygous: means having one each of two different alleles.
Dominant trait: a trait that has leadership over recessive genes.
Recessive trait: a trait that is under a dominant gene.
Probability: The chance that something will occur.
Punnet Squares: a diagram that is used to predict an outcome of a particular cross or breeding experiment. This shows dominant and recessive traits.
Reflection: This project was long but I learned a lot. Two peaks that i had was that i was always on task and didn't have a bad attitude. We did labs and experiments in class that were very interesting. Since i was having a good type i was mostly happy every day. Two pits I had were communication and leadership. I didn't really take control of situations and there was some confusion between my group mates and I. Overall this was a very fun project and i liked it because our group's suspects we found guilty were a little different. I felt proud about all the work we did with only three people.
