in this project, we figured out who killed Carelton Comet using forensic science
Presentation
Overview
In this project, we became forensic scientists and attempted to solve a murder mystery. We spent the first week discussing what forensic science was, and spent the next following 2 weeks practicing different techniques. We did fingerprint checks, DNA fingerprinting, chromotography, pedigrees, karyotypes and blood analysis. We then spent the following week creating our presentation and presented them to the class.
Reflection
One peak I had in this presentation was coloboration. My group worked very well together and we had little to no arguments over what we were doing and what work was being done. I will continue to have this same sort of work attitude to keep a cooperative group. Another peak I had in this project was time management. I was able to finish the project in a decent amount of time while maintaining a proper quality of work. I will make sure to continue to have this same quality of work so I can be able to have high quality projects
One pit I had in this project was making sure I did my share. I spent too much time not working on the project, not allowing my work to be any more than adequate. In the future I will try to be a more active member in my project and do more. Another pit I had was checking my work. This project has a lot of things that can go wrong, and I didn't make sure that everything went right. In the future I will try to ensure my work is as correct as it can be

Concepts
Fingerprinting- A style of forensic science that identifies individuals based on their fingerprints. Fingerprints are identified as three different types-loop, whorl or arch. These mixed with the specific ways the bridges of the fingerprints line up help identify whose fingerprint is whose. We used fingerprinting to identify the fingerprints on the crime scene as Nancy Normals
Ink Chromatography-A style of forensic science used to identify what complex liquids are made up of. We used ink chromatography to figure out that Nancy Normal and Sam Sophomore owned the pen that was used to right the note
Karyotypes-Karyotypes are an organization of all the chromosomes in an organism. We used karyotypes to help identify who had what diseases, and find out that Nancy Normal andCarelton Comet had diseases that were found at the crime scene
Pedigrees-Pedigrees are ancestral records used to trace who is related to who. We used pedigrees to figure out that Thomas Sandstone is actually Carelton Comet.
DNA Structure- DNA has a very specific structure. It has a phosphate backbone bound by carbon sugars, and bends into a double helix form. One side goes in a 3’ to 5’ direction, while the other side goes in a 5’ to 3’ direction. There are 4 nucleotides that are found in DNA- adenine, cytosine, guanine and thymine. Cytosine can only bond with guanine, and adenine can only bond with thymine
DNA Replication-The replication of DNA used to prepare for mitosis. It begins with helicase unzipping the DNA into a DNA fork. The primase then begins a duplication strand, and the DNA polymerase continues the rest. However, DNA is only replicated in a 5’-3’ direction, which means there is a leading and lagging strand. The leading strand goes in a 5’-3’ direction and is duplicated normally. The lagging strand goes in a 3’-5’ direction, and is duplicated in segments
Alleles- one or more form of a gene that appears from mutation. aleles help determine the phenotype and genotype of an individual, adn are passed on through parents to their child
Dominant-An allele that will express its phenotype if present
Recessive-An allele that will express its phenotype if there is no dominant gene overtaking it
Mutations-A random change in the genetic makeup of an organism. There are multiple types of mutations, all of which can be helpful or harmful.
Chromosonal Disorders- A disease that is caused by a change in the chromosomes of an individual. An example is XXX syndrome, which results from having an extra X chromosone
