For this lab, we were given a short murder case and were tasked to find the murderer. We used different pieces of evidence found at the crime scene to make connections to people and determine who was mostly likely the killer. By taking the evidence and analyzing it through fingerprinting tests, ink chromatography, Karyotype analysis, Gel Electrophoresis, and pedigree analysis, we were able to pin point the murderer and learn about different forms of testing used in forensics. We concluded that Nancy Normal was the murderer of Carlton Comet. Refer to the slideshow below for details.
Content
Forensic Science: science dealing with crime and law, involving biotechnology.
Genetic Engineering: many different techniques for moving DNA between different organisms.
Genetic Testing: type of medical testing to identify changes in genes.
Genetic Disease: an inherited medical condition caused by problems in the DNA.
Fingerprinting:Extracting the base pair of an individual's DNA for identification.
Ink chromatography: separates ink based on different or common properties.
Karyotypes: the number and display of the chromosomes in an organism.
Gel Electrophoresis:separating DNA, RNA, and protein.
Pedigrees: A family tree that shows the traits connecting the family.
Punnet Squares: Used to predict the trait most likely to be chosen.
Hereditary-
Complete Dominance: The dominant allele masks the recessive allele. (Heterozygous)
Co-Dominance: One trait is not dominant over the other, creating a phenotype which has both dominant phenotypes.
Incomplete Dominance: two alleles that don't express themselves.
Types of Mutations-
Point(single nucleotide changed) (first 3)
Frameshift(changes the frame of genetic reading)(includes deletion and insertion)
Substitution: one nucleotide is switched for another.
Deletion: a nucleotide is removed.
Insertion: base pairs are incorrectly added.
Nonsense: early stop codon.
Missense: one amino acid is changed.
Somatic: Not from the parents.
Germline:From the parents.

Reflection:
Throughout this lab, I learned lot about forensics and genetic testing. I found that our group was really efficient during this lab and overall, I am happy with how we did. One thing we could have practiced more was speaking before our presentation, that way we were more prepared and it went smoother.
I enjoyed the many different testing parts of the lab and I think my group did a good job analyzing the information. From this lab, I learned a lot about Forensics and I know understand a different career path that I wasn't aware with so deeply before.
