How do DNA samples help the csi?
CSI can use DNA samples to link a suspect to a crime scene or victim. By analyzing the unique DNA profile from a sample, investigators can identify individuals with a high degree of accuracy. This helps in solving crimes and providing evidence for prosecution.
Why DNA is so useful in forensics and identification?
D.N.A. is used to help solve crimes by the fingerprint in the DNA which can track down the person at the scene of the crime. Also, if a sample of the body is left (i.e. blood, any other bodily fluids, hair, skin) is left at the scene, through DNA finger printing, the criminal(s) involved would be identified.
Using DNA to identify who committed a crime is?
a process called DNA profiling, in which a sample is collected from a crime scene and compared to a suspect's DNA to determine if there is a match. This method is highly accurate and is commonly used in criminal investigations to establish a link between a suspect and a crime scene.
Which is not a reason that scientists use bacterial DNA rather than human DNA in biotechnology?
One reason why scientists may use bacterial DNA over human DNA in biotechnology is because bacterial DNA is often easier and cheaper to manipulate and study given its simpler structure compared to human DNA.
What technology allows scientists to compare the DNA of different kinds of organisms to determine classification?
pewp is why
What does it mean when the swab taken from you matches your DNA and the swab taken from the alleged victim matches the victim's DNA?
A swab taken from you would contain your DNA and thus match your DNA. A swab taken from the alleged victim would contain the victim's DNA and thus match the victim's DNA. What would be shocking is if the swab taken from you didn't match your DNA, or the victim's swab didn't match their DNA. Therefor, it means that you are you, and the alleged victim is the alleged victim.
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 do forensic scientists test for?
forensic scientists who are in the lab test DNA found at a crime scene to try and link a suspect to the crime scene. They test things like blood, hair, skin cells, saliva, etc.
What led scientists accepting mendel idea?
Scientists discovered chromosomes in DNA
How does DNA analysis help identify or eliminate criminal suspects?
DNA fingerprint is very specific to an individual. You can pinpoint the individual person by DNA finger print. By collecting the semen from the victim of the rape, you can identify the criminal, very precisely. From very small sample of material from the nails of the victim, you can pin point the killer, by doing the DNA finger printing. By the same theory, you can eliminate the person, who has not done the crime.

Which scientists helped to determine the shape of DNA?
The scientists who helped determine the shape of DNA were James Watson and Francis Crick.
Do scientists use real DNA?
Yes, they do use real DNA.
How can DNA be changed by scientists?
mutation
How do forensics investigators use DNA fingerprinting to link a particular suspect to a particular crime scene?
Forensic investigators use genetic markers that vary from person to person. Thus, if all of the genetic markers in the DNA from a crime scene are identical to the genetic markers in the DNA from one of the suspects, that is good evidence that the suspect and crime scene DNA came from the same individual.
How can DNA be used in crimes?
DNA is something like hair or finger prints, it makes it easier to find the suspect because only one person in the world can have a specific pattern on their finger. Even twins have different ones. Hair can be very different to someone elses. The more clues that direct to one suspect make it easier to find the truth.
Which characteristics do scientists to use to group species?
Scientists use Ancestors and DNA to group DNA.
