This murder mystery project required our best investigating skills, and taught us a lot about the different ways forensic scientists test DNA found at the scene of a crime. We practiced DNA fingerprinting, testing hair samples, blood samples, and thought critically to be able to identify the killer in the mystery.
Concepts
gel electrophoresis is a laboratory method used to separate mixtures of DNA, RNA, or proteins according to molecular size DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation Fingerprint lifting is the process of securing copies of fingerprints that are left at a crime scene Cross-matching blood refers to the test that is performed to the blood in order to determine the blood type Fingerprint lifting is the process of securing copies of fingerprints that are left at a crime scene Pedigree is the record of descent of an animal, showing it to be purebred Molarity The unit of molarity is expressed in moles per kilogram. The formula for molarity is m = moles of solute / kilograms of solvent. Chromatography is a method of separating out materials from a mixture. Ink has several dyes so we can separate those colors from one another using chromatography to find a match. Karyotypingis a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells. Extra or missing chromosomes, or abnormal positions of chromosome pieces, can cause disorders ad problems within the person. First degree murder- murder that is planned carefully, not done out of anger or in the moment
Reflection
Overall, this particular project was one of the more in depth and complicated experiments simply because there were so many different aspects and things that went into it. For the most part, my group was able to collaborate and get along well to get the project complete. Although I did struggle a bit with staying on task, I was still able to do my share of the work and get everything done in the end. I enjoyed this project because it was different and more exciting than what we normally do.
