  1. DNAFingerprinting By, Tierra, Bailey, Jenna N, and Danielle

  2. DNA Fingerprinting • In the United States, each state independently decides whether DNA can be sampled from arrestees or convicts.

  3. Laws • All 50 states require convicted sex offenders to submit a DNA sample • 44 states require convicted felons to submit DNA • 9 states require samplings from those convicted from certain misbehaviors • 11 states, including Alaska, Arizona, California, Kansas, Louisiana, Minnesota, New Mexico, North Dakota, Tennessee, Texas, and Virginia, require arrestee’s to give a DNA sample

  4. PA Senate bill • Pennsylvania Senate Bill 775, requires law enforcement to begin DNA fingerprinting of individuals upon charge for specified crimes and authorize familial searching of the state’s forensic data.

  5. Florida • A bill was signed on June 28, 2009 • Senate Bill 2276, permits the police to take a DNA sample from anyone who is merely arrested for a felony offense.

  6. What is DNA fingerprinting? • 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

  7. What they use it for… • Determine Family Relations • Detect inherited diseases • Prove guilty or innocence • Identify a dead body

  8. Examples of DNA Fingerprinting • Small Samples of • Hair • Skin • Blood • Saliva • Bodily Fluids

  9. 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

  10. Electrophoresis • The movement of charged particles in fluid or gel under the influence of an electrical field

  11. Social ramifications • Opinions on DNA fingerprinting

  12. Do you think DNA fingerprinting is good evidence for solving crimes? Why or why not?

  13. 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.

  14. 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,

  15. Should governments create DNA fingerprinting database of all citizens?31% Yes 69% No

  16. 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.

  17. No, • 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.

  18. Final Opinions • DNA fingerprinting facts from debates

  19. For DNA fingerprinting • Without it, their would be many criminals still on the loose. • Increasing populations, Identification is needed in society. • No two fingerprints are alike, so nothing can get messed up.

  20. Against DNA fingerprinting • Fingerprints can help health insurance companies test customers and charge higher rates based on if they have certain diseases. • No laws against use of genetic information, in health insurance in these states: Mississippi North Dakota Pennsylvania Washington
