How does DNA help in solving crime?
Police and other crime investigation workers can take DNA from the scene of the murder (or other crime) and check it with databases of other DNA samples and match it to a person(s) and then they have their suspect(s).
Crime scene hair is what type of evidence?
DNA
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 foresice scientists use DNA in a crime?
Forensic scientists can use DNA in a crime by collecting DNA samples from the crime scene, comparing them to DNA samples from suspects to identify potential matches, and ultimately using DNA evidence to help establish the presence of a specific individual at the scene of the crime. DNA analysis can also be used to exclude suspects or link different crime scenes together based on DNA profiles.
What can be taken as a DNA sample from a human in a crime scene?
anything
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.
Whats involved in a crime scene investigation?
"When it comes to a crime scene investigation, the events that take place are recognition of the crime scene, documentation of the scene, finding of the evidence, collection of the evidence, and finally analyzing all of the evidence collected."
What are the steps you take to investigate a crime scene?

How can DNA from a crime scene be multiplied?
DNA from a crime scene can be multiplied through a process called Polymerase Chain Reaction (PCR). PCR allows small amounts of DNA to be amplified into millions of copies, making it easier to analyze and compare with DNA samples from suspects or databases.
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 evidence can be used for DNA fingerprinting at a crime scene?
DNA evidence from blood, hair, saliva, or other bodily fluids found at the crime scene can be used for DNA fingerprinting. This evidence is compared to the DNA profiles of suspects to determine if a match exists, helping to identify or exclude individuals involved in the crime.
May link a suspect to crime scene?
DNA evidence found at the crime scene can be compared to the suspect's DNA to determine if there is a match, providing a strong link between the suspect and the crime scene. Other evidence such as fingerprints, footprints, or personal belongings left at the scene can also help link a suspect to a crime. Eyewitness testimony or surveillance footage placing the suspect at the scene can further establish their connection.
