Document Summary
Cecilia hageman, forensic science program, faculty of science, uoit. 28 years ago many things were first invented. Mostly in homicide and forensic science cases. As a forensic biologist, you cannot do much with body fluids found in a crime scene. Blood: scrape a little bit off and conduct a kastle meyer test tests for hemoglobin (just like a laminar test) Semen: spermatozoa & acid phosphatase examine cases of allegations of sexual assault. It is done by using special light sources, conducted chemically to bring out the liquid portion of the semen. Saliva: the phadebas test people cough, sneeze and spit all the time. If saliva is present, the paper used will turn blue. Amylase is a digestive enzyme, this test looks for amylase. Chemical tests include kastle-meyer, hemastix, luminol etc. (hemoglobin) Found in all biological specimens containing nucleated cells. No 2 individuals (except identical twins) have exactly the same dna. Very stable can look at cases from 10-50 years old.
