Forensic Science
Project OverviewCarleton Comet went on a picnic with Nancy Normal, Sam Sophomore, Theresa Terra, Fred Flimmer, and Glen Glee. At 7:35pm, the sky darkened and Carleton Comet was brutally murdered. On the scene, the murder weapon which was a steak knife was bagged and sent to the lab for us to analyze. The evidence we were given was the murder weapon, two blood samples, a note, a family pedigree ,and some hair . The link below will bring you to the evidence analysis.

Concepts;
Karyotypes- The general appearance and arrangement of a person's chromosomes, which could be used to identify any chromosomal diseases.
XXX Syndrome- The presence of an extra X chromosome in a woman, which results in a lowered IQ, speech impediments, learning disabilities, and less emotional and behavioral control.
XXY Syndrome- The presence of an extra X chromosome in a man, which results in slight bodily disfigurement, infertility, and the development of breasts.
XYY Syndrome- The presence of an extra Y chromosome in a man, resulting in weak muscle tone, impaired motor skills, developmental issues, and difficult speech.
Down Syndrome- The presence of an extra 21st chromosome, resulting in impairments to physical and mental development, poor muscle tone, unproportioned facial features, and eyesight issues.
Pedigree- A chart of a person's family history, used to track and determine the presence or likelihood of a person inheriting a genetic disease.
Huntington's- A hereditary disorder resulting in the deterioration of nerve cells, leading to personality changes, anxiety, aggressive behavior, delusions, and mood swings.
Marfan Syndrome- A genetic disorder affecting a person's connective tissue, resulting in distorted facial appearances, eye problems, the crowding of teeth, a thin body, and disproportioned arms, toes, and fingers.
Dominant- An allele which, when present in a pair of alleles, will be expressed regardless of the pairing.
Recessive- An allele which, when present in a pair of alleles, can only be expressed when both alleles are recessive.
Gel Electrophoresis- The technique of separating DNA by component length using an agarose gel, TAE buffer, and electricity to draw the DNA towards the positive end through the gel.
DNA- Deoxyribonucleic acid, which is the building block of the human genome and determines everything about us, from size to gender to hair color.
Blood Types- A, B, AB, or O, based on the presence of antigens on the red blood cells. Antibodies react by attaching to the respective antigen, so a person with A-type blood would not be able to give blood to a person with B-type blood, as the second person's antibodies would attack the A-type blood.
Homicide- The murder of another human being.
First-Degree Murder- Any unlawful killing that is both willful and premeditated. (Eg. Assassinating someone, or coming up with a plan to murder them and carrying it out.)
Second-Degree Murder- An intentional killing that is not premeditated nor committed in the heat of the moment or caused by dangerous conduct and the offender's lack of concern for human life. (Eg. A person is trying to shoot someone, but another person gets caught in the crossfire.)
Third-Degree Murder- Any intentional killing that involves no prior intent to kill, and which was committed under such circumstances that would cause a reasonable person to be disturbed or traumatized. (Eg. A man gets in a bar fight after learning that his wife has been cheating on him with his best friend, and the fight results in the death of the "friend".)
Fourth-Degree Murder- A killing that stems from a lack of intention to cause death but involving an intentional, or negligent, act leading to death. (Eg. A person gets drunk, and knowing that they are intoxicated, go driving out on the highway and crash into a car, resulting in the death of the other driver.)
Ink Chromatography- A process that can be used to separate the components of the ink of a pen, accomplished by placing a strip of chromatography paper with an ink dot in some alcohol, which would diffuse upwards and carry the ink along with it.
Reflection
One thing that I could work on is not getting distracted by other groups. This has been a problem for me all year and not only am I distracting myself I'm distracting the other group. One other thing that I did well was that I was able to find a motive that supported out claim, which made our presentation that much stronger. This took a lot of work, in the form or reading through all the family trees and figuring out who hated who and why. Another thing I could work on is my productivity once we get something done cause I'll just go straight to my phone and screw off, which does lead to problems as you would imagine. If I can work on this for the next presentation, I will be able to do a much better job in the future.
