Forensics

What is it?

DNA testing through Forensics is when any organism can be identified with a DNA examination sequence that is unique to that species. Identifying individuals within a species is not as hard. As technology advances, DNA tests are getting closer and closer to being able to allow precise individual identification.

Forensics is the use of DNA for identification.

How does it work?

Scientists use samples from blood, bone, hair, and other body tissues and products to tests with. They find the markers in a DNA sample by designing probes (small peices of DNA)that will find and bind to a complementary DNA sequence in the sample. The series of probes binds to a DNA sample and then creates a distinctive pattern for an individual. Forensic scientists compare these DNA profiles to determine if the suspect's sample matches the evidence sample.

What does it do?

This is used in many cases. Forensics gather items and information from a crime scene of potential suspects whose DNA may match the evidence left at the crime scene. This can exonerate persons wrongly accused of a crime or identify crime and catastrophe victims. DNA tests can also establish paternity and other family relationships. It can detect bacteria and other organisms that may polute air, water, soil, and food. DNA tests can also match organ donors with recipients in transplant orginizations

What is it?

The use of science and technology to investigate and esablish facts in criminal or civil courts of law. Forensics or forensic science is the application of science to questions which are of interest to the legal system. Forensic science is any aspect of science as it relates to the law.

How does it work?

  1. Isolate the DNA.
  2. Cut the DNA up into shorter fragments containing known VNTR areas.
  3. Sort the DNA fragments by size.
  4. Compare the DNA fragments in different samples.

The way we sort by size is gel electrophoresis

  1. DNA is isolated from a sample such as blood, saliva, semen, tissue, or hair.
  2. The huge genome is cut up with restriction enzymesmanageable DNA fragments
  3. These DNA fragments are then sorted by size using gel electrophoresis.

What is Forensic Science?

Definition- any aspect of science as it relates to the law

How Does Forensic Science Work?

Forensic Identification- when scientists scan DNA sequences that are unique to that specimen and try to match those scanned sequences with the sample from the crime scene.
