Recommended: Crime scene investigation process

The evidence of this lab has given me the conclusion that Dr. Ward has been murdered. The primary suspect based on the research of the crime scene would be Miss White, his secretary. The purpose of this lab was to allow the class to experiment with DNA samples as well as fingerprints and hair samples to come to a conclusion of who had killed Dr. Ward based on our own experiments and research. The main pieces of evidence leading to Miss White(S3) being the primary suspect are the hair samples as well as fingerprint 2 on coffee cup. Fingerprint 1 looks like a mix of fingerprints while fingerprint 2 looks like a whorl which could be linked to S3 as being the suspect. Hair sample 1 is not a human hair but a cat hair. S1 has a cat of her own, S2 …show more content…

After its melted and you don’t see any clumps you pour it into the mold to cast the gel and wait 20-30 minutes for the gel to set. Plug in your electrophoresis system and assemble the platform in the tank. After the gel sets remove it from the casting stand, setting the gel tray inside the tank on the platform making sure the wells are facing the negative side. Measure out 125 ml of diluted SB running buffer and pour slowly into one side of the tank, removing all air bubbles. Turn on the low intensity light and load your DNA samples using 10 μl per well, changing your pipette tip after every sample. Put on the photo hood and press the power button which activates a green light, let the gel run for 25-30 minutes or until DNA separation is sufficient. Use the photo hood to take a picture with a cell phone or camera. Fingerprint 1 is a mixture of prints and can not be depicted on who it belongs to. Fingerprint 2 is a whorl print, it can belong to Miss White. Microscope Image of Hair 1 is from a cat, belonging to Dr. Powell’s cat or Miss White’s Boyfriends cat. Microscope Image of Hair 2 is a dark brown human hair, belonging to Mrs. Fischer or Miss White. The DNA sample from Hair 2 is a direct to Miss White’s DNA

We came to this conclusion not after our recordings of our observation, we also added drops of various indicators to each substance sample. By doing this, we were able to see the various reactions with each indicator to see which substance matched the reactions of the unknown substance found at the crime scene. The substance at the crime scene reacted with bubbling when each indicator, as did the Acetylsalicylic Acid, confirming the identity of the substance At the crime scene we also found a series of blood spatters as well as a pool of blood near Anna’s head. Not only did the blood provide us with DNA evidence, we were able to conduct a series of tests allowing us to figure out whether Anna fell and started bleeding or was already on the

Bikerman And Maroon Flash Case Study Examples

585 Words | 3 Pages

Introduction During the investigation of who hit Reveille, 2 suspects (Bikerman and Maroon Flash) were inspected using gel electrophoresis to create a DNA fingerprint, fingerprint analysis, probable blood evidence analysis, and hair analysis. DNA Analysis In developing a DNA fingerprint using gel electrophoresis for Reveille’s, Bikerman’s, and Maroon Flash’s DNA, and DNA on Reveille’s fur, Bikerman’s shirt, and Maroon Flash’s shirt, the restriction enzyme fragment length polymorphisms were separated and the DNA evidence was compared to the known samples of Reveille’s, Bikerman’s, and Maroon Flash’s DNA. (This can be seen in the picture attached to this report of the gel electrophoresis.)

The apparatus was then closed and turned on to run at 100 volts. Electrophoresis ran for 30 minutes; separating the DNA according to size in the gel. Then the tray with the gel was removed and a stain sheet was placed on the gel for 15 minutes. After 15 minutes that gel was rinsed with water and then set in water. Later, 20 to 30 minutes, the gel was view over a light box to view how far the bands traveled.

The Pros And Cons Of Dna Profiling

946 Words | 4 Pages

Today, arguments for and against the use of DNA have surfaced. DNA profiling is the technology that uses the individual’s DNA characteristics. Each human has his own DNA, comprising 99.9% of the same DNA but scientists have found the remnant 0.1% difference. One of its benefits is that scientists are using this crucial distinction to find criminals from bodily fluid samples, hair, skin and other parts of the body. (sciencemuseum, 2016) DNA also has another advantageous application; it is used to find biological family relationships.

The past decade has seen great advances in a powerful criminal justice tool: deoxyribonucleic acid, or DNA. DNA can be used to clear suspects and discharge persons mistakenly accused or convicted of crimes (“Using DNA to Solve Crimes”). When used to its full potential, DNA evidence will help solve and prevent some of the United States of America 's most serious violent crimes. DNA is generally used to solve crimes in one of two ways. In cases where a suspect is identified, a sample of that person’s DNA can be compared to evidence from the crime scene.

But as this method requires a large amount of material and has low quality results, many cases could not be solved, particularly when only little biological material samples were collected in a crime scene investigation. The application of polymerase chain reaction (PCR) widened the scope of Forensic genetics as it makes it possible to amplify small and traces amount of DNA samples. STR testing has revolutionised forensic case work on human identification and paternity tests. [2] In addition newer DNA tools, including mitochondrial DNA and SNP (Single nucleotide polymorphism – replacement, insertions or deletions that occur at single position in the human genome) might be used when STR fails to yield a result or when only a partial profile is obtained for the size and condition of the sample.
