Alphonse Bertillion developed a method of recording physical features of a person in such a way that the record would be unique to that person. It consisted of taking measurements of various parts of the body‚ such as the head‚ shoulders‚ fingers‚ and skull. This method was referred to as Bertillionage‚ after its creator. Bertillion developed a set of precise measuring instruments to be used with his method. The Bertillionage system became very popular throughout Europe and the United States

The Scientific Method in Relation to Fingerprinting Although no one scientist is recognized as the inventor of the scientific method‚ its use in the scientific community believes to date back to 384-322 B.C. During this time‚ Aristotle recognized the importance of deriving reliable knowledge based on observation. As time progressed to the 1200s‚ Roger Bacon acknowledged the significance of the repeating cycle of observation‚ hypothesis‚ experimentation and verification‚ a scientific method that

An example of modern forensics evidence is the use of DNA fingerprints. Sources of DNA include blood‚ hair‚ semen‚ saliva‚ bone and tissue. Each person has a unique DNA fingerprint. A DNA fingerprint is the same for every cell‚ tissue‚ and organ of a person. It cannot be altered by any known treatment. Consequently‚ DNA fingerprinting is rapidly becoming the primary method for identifying and distinguishing among individual human beings . An additional application of DNA fingerprint technology is the diagnosis of inherited disorders in adults

Samantha Meyer Lesson Plan 8/Reflection #8 SCIE 376 This week‚ I taught a lesson about fingerprinting to my students and it went extremely well. The students were highly attentive‚ every student participated‚ and based off of my assessment‚ every student fully understood the topic. My lesson this week aligned with the scientific and engineering practices 1‚ 2‚ and 4. Practice 1 is asking questions‚ practice 2 is developing and using models‚ and practice 4 is analyzing and interpreting data. My

Review of 53BP1 inhibitory mechanism in Homologous Recombination in Brca1-Deficient Cells by Blocking Resection of DNA Breaks and Its Chemotherapeutic Implication BRCA1 is tumor repressor gene and plays an important role in breast cancer development. In the DNA double-stranded break (DSB) repair‚ loss of BRCA1 contributes to defective homologous recombination (HR) and predominant non-homologous end-joining (NHEJ)‚ which leads to significant defects in genomic stability with increased amount of

Fingerprinting Powders Prac Write Up- Amy Clark Aim: To discover which powder works best to take fingerprints on a glass surface. Hypothesis: The cocoa will work best because we’ve seen it used in lots of tutorials. Theory: There are 3 main types of fingerprints. Loops are the most common. They start on one side of the finger and come back around to finish on that side of the finger as well. Around 70% of fingerprints are loops of some type. Whorls are the next most common with around 25% of fingerprints

Libby Copeland‚ the author of “Who Was She? A DNA Test Only Opened New Mysteries”‚ wrote about Alice Collins Plebuch’s DNA testing story by using a specific tone and word choice. Libby Copeland used a formal‚ yet friendly tone within her writing piece. This helps to maintain a professional and sophisticated mood. It also appeals to the readers of the article‚ and it is very appropriate to use this tone‚ considering that it was in the newspaper‚ The Washington Post. Because Copeland is telling a

Report August 28‚ 2013 DNA Extraction on Onion (Allium cepa) and Human Cheek Cell Arriza‚ Rolland Merch Buscato‚ Carl G. Butil‚ Conrad G. Leonida‚ Renee Theresa ABSTRACT This activity observes the DNA present in onion (Allium cepa) and human cheek cells by extracting it with the addition of lysis buffer and chilled ethanol. The lysis buffer is prepared from squeezed onion mixed with salt and Pantene Pro-V Shampoo. The buffer degrades the protein enveloping the DNA found in onion and cheek
