DNA fragments are most commonly amplified using a technique called "polymerase chain reaction," or PCR.
In PCR, a special DNA-replicating enzyme called a polymerase is used to copy short pieces of DNA over and over again, increasing the number of fragments exponentially with each cycle. Primers (even shorter strands of nucleic acids that match up to short regions on the DNA being amplified) tell the polymerase which part of the DNA to copy.

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?
Using DNA to identify who committed a crime is?

How you separate separate aluminium pieces from salt?
One commonly used method to separate aluminium pieces from salt is by using a magnet. Since aluminium is not magnetic, the magnet can attract and separate the aluminium pieces from the salt. Another method is to dissolve the salt in water and then use filtration to separate the larger aluminium pieces from the saltwater solution.

Can you give me an example of a sentence using the word flee?
I will flee the scene of the crime.
What is the difference between a criminal investigator and forensics?
Investagator looks for clues/facts using data from the crime scene Forensics works with the body from a crime scene gathering data
What are forensics?
study of all material substances, especially at a crime scene using DNA and such.
How do crime scene investigators fingerprint?
Crime scene investigators use techniques like powder dusting, cyanoacrylate fuming, or ninhydrin spraying to develop latent fingerprints at a crime scene. They then lift the developed prints using adhesive tape or specialized fingerprint lifting tools for analysis and comparison.
What kind of sentence can you make using the word guiltlessly?
I guiltlessly walked away from the crime scene.
A sentence using the word cordon?

How can environmental scientist use DNA technology?
by using pcr to analyze DNA at a crime scene
An example of a sentence using the word systematic?
A thorough and systematic investigation of a crime scene is necessary to find evidence linking a suspect to a crime.
How is a crime scene analyzed?
A crime scene is analyzed by documenting and collecting physical evidence such as fingerprints, fibers, and DNA samples. Investigators also photograph the scene from different angles, sketch the layout, and interview witnesses. All evidence is then analyzed in a forensic lab using specialized techniques to help solve the crime.
