Why is DNA important?
DNA is like the "blue prints" of a person. Almost everything that happens in your body is based on DNA. It could be used to identify people. It could be used to find out if someone is someone's child, parent or other relative. It is often used to solve crimes. A hair or blood found on the crime scene could match the DNA sample of a suspect who is claiming he's never been at the scene. It could also be used to find genetic diseases.

What evidence can be used for DNA fingerprinting at a crime scene?
Vagina
How can environmental scientist use DNA technology?
by using pcr to analyze DNA at a crime scene
When DNA profiling is carried out the second DNA sample the one not collected at the crime scene is called the?
mitochondrial sample
How do DNA samples help the csi?
DNA samples help the CSI because if they found some DNA at a crime scene they could match it to a person.
How is science used in crime scene investigation?
DNA technology allows you to scan DNA, such as fingerprints or hair or blood, and it gives you matches of people that could be the suspect.
Why can the presence of hair at a crime scene associate a suspect or victim with the crime scene?
Hair found at a crime scene contains DNA, which can be compared to a suspect's or victim's DNA to establish a link. Hair also has unique characteristics like color, length, and treatment, which can be used as evidence in investigations. Analyzing hair evidence can help to identify individuals present at the crime scene.
What is the name of the job where you take DNA of a crime scene?
The name of the job where you would take DNA from a crime scene is called a Crime Scene Investigator.
How is DNA fingerprints used to solve crimes?
DNA fingerprints are used in forensic investigations to link suspects to a crime scene or to eliminate suspects. By comparing the unique patterns of DNA found at a crime scene to those of potential suspects, forensic analysts can establish if there is a match, helping to identify or rule out individuals involved in the crime. This scientific method provides strong evidence for solving crimes and is a valuable tool in the criminal justice system.
What process could you use to amplify the DNA in a bloodstain from a crime scene?
PCR
What is the purpose of a gel electrophoresis?
to separate a mixture usually that of DNA so that it can be found to correspond with that found at a crime scene
Does match to crime scene DNA mean the person is guilty?
Not necessarily DNA match could mean the person was there before but it does not necessarily mean they were part of the crime
How is DNA use as Evidence?
They compare the DNA of those found at the scene of the crime against any suspect. This can be achieved by using Electrophoresis.
What are the benefits to using DNA to solve crimes?
The DNA of each individual is unique. No two individuals share the same genetic make up unless they are identical twins. Analyzing DNA samples found at a crime scene can help place a suspect at the crime scene. If it can be legally proven that a suspect was present at a crime scene, there is practically no refutation to this finding. DNA test data is very valuable in court. But if you were never at the scene of the crime how can they prove you were anyone could have put it there?
What could you find on an shoe or clothing left at a crime scene?
You might find DNA, or even a fingerprint.
How can DNA from a crime scene be multiplied?
DNA from a crime scene can be multiplied using the PCR (polymerase chain reaction) technique. See the Related Link below.
