Intro.
This projected was based on the investigation of a mock murder. We were tasked with finding the murderer using basic forensic sciences and biology. We used DNA fingerprinting, blood types and karyotypes to find information that could lead us to the murderer. WE learned these topics from the multiple experiments we did during class and lectures. We ended up finding the murderer and charging them with first degree murder.

Concepts.
DNA Fingerprinting- It is the use of someone's unique DNA to identify certain individuals. This can be blood, hair or any part of the body that contains DNA.
Ink Chromatography- Ink chromatography is the process of finding out the different pigments in an ink. Even though inks re the same color they could be made up of a variety of pigments mixed together.
Karyotypes- This is an appearance of the chromosomes in a organism. this can be used to find if someone has chromosomal disorders.
Pedigree- it is a chart that shows all persons relatives along with any genetic diseases.
DNA Structure- DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base.
Dominant Genes- Genes that are always expressed if present. if you inherit only one it will always be present.
Recessive Genes- Genes that wont always show up if present. you must inherit 2 recessive genes for them to show up.
Alleles- it is a variant form of a gene usually caused by genetic mutations.
DNA Mutations- Are random changes in one's genetic makeup. usually formed during the copying stage.

Reflection.
I liked working on this project We did a lot of experiments which I particularly enjoyed. One positive of this project was how well our group worked together. We had no arguments and everyone did their fair share of work. One downside for me was that i ended up missing a few days during the end of the project so i wasn't as prepared for the presentation as the others. Overall i liked working with my group and i really enjoyed this project.
