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.

DNA analysis compares genetic material found at a crime scene with samples from potential suspects to determine a match. If DNA collected from a suspect matches the DNA evidence from the crime scene, it can help identify the individual as a likely perpetrator. Conversely, if there is no match, the suspect can be eliminated from the investigation.

What is the role of science criminalistic in criminal justice?
Forensic science plays a crucial role in the criminal justice system by providing scientific analysis of evidence found at crime scenes. This evidence can help identify suspects, corroborate or refute alibis, and support prosecution or defense arguments in court. Forensic techniques such as DNA analysis, fingerprinting, ballistics, and toxicology help investigators solve crimes and bring perpetrators to justice.
What is the role of chemistry of criminology?
Chemistry in criminology plays a crucial role in analyzing evidence like drugs, explosives, and toxins found at crime scenes. It helps identify substances, link them to suspects or crime scenes, and provide evidence for prosecution. Analytical techniques such as chromatography and spectroscopy are commonly used in forensic chemistry to solve crimes.
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 is the role of the forensic science service in the criminal justice system?
The forensic science service plays a crucial role in the criminal justice system by providing scientific analysis of evidence collected from crime scenes. This analysis helps investigators and prosecutors establish facts, identify suspects, and present evidence in court. It helps ensure that justice is served through the use of unbiased scientific expertise.

What examination of bite mark evidence and its relation to a criminal investigation is known as?
The examination of bite mark evidence in relation to a criminal investigation is known as forensic odontology. This field involves the analysis and comparison of bite marks found on a victim or at a crime scene to potential suspects through dental records or bite mark patterns. The goal is to provide valuable evidence to aid in identifying or eliminating suspects in criminal cases.
What does crime scene mean in forensic science?
A crime scene in forensic science is the location where a criminal act has taken place and where forensic investigators collect and analyze evidence to reconstruct what happened. It is crucial for preserving and documenting evidence that can help solve the crime and identify suspects. Crime scene analysis is a fundamental part of forensic investigations.
What are the goal of criminal investigation?
The goal of criminal investigation is to gather evidence to determine if a crime has been committed and to identify and apprehend suspects. Investigators aim to gather enough evidence to support a prosecution in court and ultimately achieve justice for victims and ensure public safety.
Why are fingerprints importannt?
One major use of fingerprinting is related to criminal investigations. fingerprints can often be used to identify the perpetrator of a crime. Fingerprints are used to identify unknown victims, witnesses or suspects, to verify records, and most importantly, as links between a suspect and a crime.
What is the impact of DNA analysis on society?
DNA analysis enables law enforcement to place offenders at the scene of a crime (or eliminate suspects that are innocent), can lead to crimes that were previously not solveable to be solved, and can determine the paternity of children. It can also determine genetic diseases and possibly lead to cures for those diseases.
