SCIENTIST

Technique that is used to identify patterns that occur in DNA

Called fingerprinting because no two person’s genetic code is the same

Procedure where by the genetic information in a person’s cell analyzed and identified

What is DNA fingerprinting?

Who?

DNA started back in 1985

It was developed by Sir Alec Jeffery’s in England

What they use it for…

Determine Family Relations

Detect inherited diseases

Prove guilty or innocence

Identify a dead body

EXAMPLES OF DNA FINGERPRINTING Small Samples of

Hair Skin Blood Saliva Bodily Fluids

TECHNIQUE OF FINGERPRINTING DNA extracted from the sample being used

Requires DNA to be cut up into small fragments

Its then arranged by size using a process called electrophoresis

Then segments are then marked with probes and exposed on X-ray film, where they form a characteristic pattern of black bars

ElectrophoresisO The movement of charged particles

in fluid or gel under the influence of an electrical field

Opinions on DNA fingerprinting

Do you think DNA

fingerprinting is good

evidence for solving crimes?

Why or why not?

YES,

DNA fingerprinting is good evidence for solving crimes because the DNA can find a person and if that person did something bad they will get sent away.

DNA fingerprinting can identify anyone and show whether they are related.

DNA evidence is not an infallible tool for criminal investigations, experts have warned.

A magazine sent a sample of DNA from a real crime to 17 experienced analysts in U.S. The DNA was used to convict a man from a gang rape, but only 1 out of 17 had the same conclusion. Four said the evidence was inconclusive and 12 he could be excluded.

No,

Should governments create DNA fingerprinting database of all citizens?

31% Yes 69% No

Yes,

• Some people said yes because victims of accidents or natural disasters could be easily identified.

• There would be a result in solving unsolved crimes of rape and murder.

Others said no because DNA being on file is losing privacy, it would make some people feel like criminals with their fingerprints in the system.

Also, hackers could get a hold of it and use it against someone.

No,

Final Opinions

Increasing populations, Identification is needed in society.

No two fingerprints are alike, so nothing can get messed up.
