In this project we were given a fake murder to investigate where we had to use forensic skills to solve the case. In the duration of this project we used different forensic skills such as chromatography, karyotyping, blood testing, hair analysis, fingerprint analysis, and DNA fingerprinting. In this project we had several subjects, and in the end we had to use the data that we collected to convict someone of the murder of Carlton Comet.

Key Concepts:
Ink Chromatography:
It is a method of separating out materials from a mixture of several dyes to see individual colors of ink
Blood Typing:
The classification of the type of blood a human has by looking at their antigens
DNA Fingerprinting:
Is a forensic technique used to identify individuals by characteristics of their DNA
Fingerprinting:
We investigated different types of fingerprints such as arches, whirls, and loops to identify and match the finger prints left of the murder weapon
Pedigree:
The background or history of a person or thing
Karyotypes:
the number and visual appearance of the chromosomes in the cell nuclei of an organism or species
Genetic Mutations:
A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people
Complete Dominance:
It is a form of dominance in heterozygous condition wherein the allele that is regarded as dominant completely masks the effect of the allele that is recessive
Co-Dominance:
When two traits are both dominant are both expressed
Incomplete Dominance:
When neither trait is dominant over the other and are expressed together
Phenotype:
the set of observable characteristics of an individual
Genotype:
the genetic make up of an individual organism

Genetic Mutations:
A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people
- Point: single nucleotide change
- substitution: one nucleotide for another
- nonsense: early stop codon
- missense: one amino acid is changed
- Frame shift: Changes the frame of gene reading
- insertion: nucleotide are added
- deletion: nucleotide are take
Complete Dominance:
It is a form of dominance in heterozygous condition wherein the allele that is regarded as dominant completely masks the effect of the allele that is recessive
Co-Dominance:
When two traits are both dominant are both expressed

Reflection
Some peaks in this project was that I was able to lead my group, made sure we were on task, and I learned a lot of valuable information from this project like how to fingerprint a person. I was able to lead my group by making sure that everyone had an equal part in the project.
Some pits of this project was that I needed to make sure that everyone in my group understands something before we move on and we needed to work better with each other. I needed to make sure that everyone in my group understood something before we move on because we would move on and then I would need to re-explain protein synthesis and that took more time than if I made sure everyone understood the concept the first time. Even though we were productive we could have worked better with each other because most of the time we work independently and we did not work as a group. Next time I will do a better job checking in on my group members.
