FSC239Y5 Lecture Notes - Lecture 6: Dna Profiling, Hand Geometry, Silver Chloride
Document Summary
General pattern is the same, but during the process chemical stimuli interacts with it and so every finger print is unigue: idivisualizing features of fp. history: ancient babylon in the second millinium bce, before 851 ce. Canadian mounted police convinced his superiors in the rcmp. Fp minutiae: one fr pattern found, number of features call min used to compare the fp and decide whether from same person or not, eidges end abruptly--ending ridges, splitting into 2-- bifurcation or fork, dot, lake, delta. Special illumination: simple oblique illumination, alternate light (special frq, monochromatic light. Bloody fingerprints: dont need enhacement, reagents used based on oxidase rsns, dna profiling of the blood by pcr. Fingerprint identification: unique, unchangable, partially genetic, but still unique, after birth or minor injuries they stay the smae. -- examiner should first determine the suitability from fr, then do a:analysis,
