DNA "Fingerprinting"/ DNA Profiling Flashcards
Advantages of DNA fingerprints over ordinary fingerprints
What is a DNA Profile
DNA fingerprints is a pattern of black bars left on an X-ray film when an extract of DNA is put through a special biotechnical process
DNA Profiling is a method of identifying an individual by comparing his/her DNA profile with another known DNA fingerprint
How is a DNA profile made
Small segments of DNA are marked with radioactive probes and exposed on X-ray film
The pattern of Black bars left behind on the X-ray film is the DNA profile
If the DNA profiles produced from two different samples match, the two samples probably came from the same person
What are the uses of DNA profiles
Diagnosis of inherited Disorders
Developing Covers for Inherited Disorders
Biological Evidence
Identification of Relatives
Some debates around DNA Profiling
Since only a small piece of DNA is analyzed, a DNA Profile may not be unique to an individual
DNA profiling performed in private laboratories may not follow uniform testing standards and quality control
Since Human Beings must interpret the test, human error could lead to false results
DNA profiling is expensive, suspects who are unable to provide their own DNA experts may not be able to adequately defend themselves against charges based on DNA evidence
DNA analysis might reveal personal information such as the presence of HIV/AIDS and this could be used against the person because of prejudice against persons with the disease
