Transcript of DNA Fingerprinting
By: Britney, Sky, Laila
How it Works!
A person's finger print is unique so as his DNA. The chemical structure of person's DNA is the same; however, the only difference is the order of pairs. There are so many millions of base pairs in each person's DNA that every person has a different sequence.
Current research is investigation genetic Mutation and Recombination of DNA and sperm and egg cells.
Scientists believe that the Black Plague could have included a genetic component.
Research of other genetic diseases.
Cancer moving through the blood.
In September 1984, Dr. Alec Jeffreys, a geneticist from the University of Leicester in Great Britain first discovered DNA Fingerprinting.
History of DNA Fingerprinting
The DNA alphabet is made up of four building blocks – A, C, T and G, called base pairs, which are linked together in long chains to spell out the genetic words, or genes, which tell our cells what to do.
The top left picture is a DNA fingerprint that was found at a crime scene. DNA Fingerprinting is a way of finding out who was at the crime, and as you can see suspect 3 is guilty.
It is often used to track down the genetic basis of inherited diseases. If a particular pattern turns up time and time again in different patients, scientists can narrow down which genes might be involved.
It can also be used to screen parents that might have inherited abnormalities, such as Huntington’s disease or muscular dystrophy, so appropriate precautions can be made.
What is it used for?
Used to determine if a family relationship exists between two people.
It is very unlikely that two people would ever have the same fingerprint.
It also applies to other organisms. Plants, animals, even bacteria.
The analysis of DNA from samples of body tissues or fluids in order to identify individuals.
What is it?
and fighting crime
Nations across the globe use databases containing DNA fingerprints to catch criminals.
In America, every convicted felon is required to submit a DNA sample for comparison against all future crimes.
How DNA Fingerprinting has changed our world
It has made crime solving much quicker, and much more efficient.
It has increased our understanding of genetic traits and diseases.
Allows for almost concrete answers in questions of genetic diseases and conditions.
