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.
How do they use DNA evidence today?
Police use DNA evidence to run tests and find out who committed a crime.
What are the benefits and the limitations to using DNA to solve crimes?
The benefits of using DNA to solve crime are many. Every human has their own DNA which means that no matter how well someone tries to hide their identity, they can never change their DNA. This translates to being able to use DNA to track down a criminal or identify a victim's body. The limitations of the process are many though as DNA can wash away before it is collected.
What was the impact of DNA fingerprint?
DNA finger printing or DNA typing is very powerful technique that uses DNA markers. Forensic people benefit from this technique as it can be used to identify a paternity and also DNA samples from the crime scene can be matched with that of a suspect. DNA polymorphism is the main aspect that is focused on in this technique.
How is DNA useful in Criminal Justice?
DNA is the genetic makeup of every human. It is VERY similar, but still different. It is original and unique to every person, therefore it can be used to identify someone. If i were to leave a strand of my hair (a DNA sample) someone could find out who i was through the strand of hair i left behind. It is useful in criminal justice because it can be used to identify a person in a crime. or to prove that a person was at a crime scene :) Hope this helped!
How has the discovery of DNA benefited mankind?
Th discovery of DNA has benefited mankind by allowing us to know who committed a murder, a rape, or any other crime. It has also helped with knowing who a person is if the face is beyond recognition from a bad burn or if they have no id on them.
How does using DNA compare to using other older methods?
DNA can be extracted from anything that came from the body, such as skin and bodily fluids. It can accurately identify a suspect because no one shared the same exact DNA. Older methods such as fingerprinting are still used but it only works if there were fingerprints left on the crime scene.
How can environmental scientist use DNA technology?
by using pcr to analyze DNA at a crime scene
How can DNA from a crime scene be multiplied?

What can't DNA profiling be used for?
DNA profiling is used by forensic experts to identify an individual. This technique is mostly used for parental testing and crime investigation.
Under what circumstances are DNA fingerprints used?
In most cases DNA fingerprints are used in identifying crime suspects. If there are fingerprints left at a crime scene then DNA fingerprints are used to attempt to identify the suspect. There is a database of criminal fingerprints that prints can be matched to if they are in the database.
Why can the presence of hair at a crime scene associate a suspect or victim with the crime scene?
hair can help to find the person who committed a crime because of the DNA that is found in hair.
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.

What are forensics?
study of all material substances, especially at a crime scene using DNA and such.
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.
