1. DNA fingerprinting

2. What is DNA fingerprinting?
DNA fingerprinting is a laboratory technique used to link biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. If the two DNA are a match, then the evidence came from that suspect.

3. The test is used to determine whether a family relationship exists between two people, to identify organisms causing a disease, and to solve crimes. Only a small sample of cells is needed for DNA fingerprinting. A drop of blood or the root of a hair contains enough DNA for testing.
FOR WHAT?

4. How is it used?
They can compare the DNA in samples found at a crime scene with DNA from possible victims and suspects. By comparing DNA’S, they can link victims to crime scenes. FBI and police labs around the us have begun to use DNA fingerprints to link suspects to evidence- blood or semen stains, hair or items of clothing found at the scenes of a crime. Since 1987 more than 150 cases have been closed with the use of DNA fingerprinting evidence.

5. DNA fingerprinting is now used as a routine to solve crimes
DNA fingerprinting is now used as a routine to solve crimes. In recent years, new stories have reported how a lot of DNA has been used to identify individuals involved in crimes.

6. Pros of DNA fingerprinting:

7. DNA evidence used during a criminal trial can be used both for convincing of guilty and convincing of innocence.

8. DNA fingerprinting for hereditary diseases can give medical professionals the information they need to help patients delay or prevent diseases.

9. paternity can be established.

10. CONS OF DNA fingerprinting:

11. the accuracy of DNA fingerprinting testing is dependent on experience and lab equipment.

12. DNA can degrade over time which would result in inaccurate information

13. inaccurate DNA results could convict an innocent person of a crime.

14. I think they should definitely use DNA fingerprinting
I think they should definitely use DNA fingerprinting. It can help us get closer to the clues faster. They are able to get so much information from it. It is very useful for our society needs. It breaks everything in simple terms.
