Forensic science utilizes DNA testing to help identify criminals by comparing DNA evidence collected from a crime scene with that of a suspect. This process can prove or disprove a match, aiding in investigations and providing evidence for criminal cases.
they can match the footprints to footware of suspects
Forensic scientists need to know about DNA, how to calculate density, and other science things to be able to perform their jobs well. If they don't know ANY science, it wouldn't help solving a crime because they would, for example, need to match DNA to another person's.
Yes, blood type is reliable and accurate. When forensic scientists collect blood from the crime scene and/or the victim (blood is an example of "physical evidence"), they use the blood to match it up with whoever was at the crime scene. It could belong to either the victim--who might have died a violent death--or it could belong to a suspect.
Very important. A fingerprint is a step away from solving a crime, unless the fingerprint belongs to the victim. But, if someone was apparently murdered, and criminal investigators find fingerprints around the scene, they use those prints to match up to another person's prints, to figure out if this person is a prime suspect to the crime.
Fingerprint examination is considered well established in forensic science because of its reliability, uniqueness, and permanence. Fingerprints are unique to each individual, ensuring accurate identification, and the patterns do not change over time. The extensive databases of fingerprints make it easier to match and identify suspects, making it one of the most reliable forms of evidence in forensic investigations.

Most religions provide a story about how the world was created - all these religious stories do no match up with the factual, observable evidence about how the world was created (the subject of Earth Science). Thus the development of Earth Science (indeed science in general) has lead to people falling away from belief in the religious explanations for things and sadly from religion itself.
The Criminal Justice (CJ) system includes law enforcement agencies, DA's, lawyers, jails and prisons, courts, public records and administration, probation and parole officers and all other connected agencies and services. These are collectively referred to as the 'criminal justice system', from first offence to conviction and beyond. Forensic Science is the science and technical aspect of criminal justice. Where CJ is in its entirety, the legal arm which investigates the crime, proposes a theory of the crime, and brings justice to the victim and a conviction of the perpetrator, Forensics basically collects the evidence and tests that theory. The outcome of forensic testing and evidence collection can piece together the crime as it happened. Once those pieces have been put together, the theory can either be proven, disproven or it can perhaps suggest a new theory altogether. In this case, the new theory is tested and investigated to be sure of a match. If there is no match to the suspect and victim, then the investigation continues until a match is made. If a match is made the Criminal Justice system works to bring the perpetrator to justice.
Forensic serology is the branch of forensic science that deals with the identification and analysis of bodily fluids such as blood, semen, and saliva found at crime scenes. Serology techniques are used to determine the blood type of an individual or to match bodily fluids to a specific person. These findings can be crucial in criminal investigations to link suspects to a crime or exclude innocent individuals.
Purposes of DNA fingerprinting include; · Medical research · Diagnose inherited disorders · Develop cures for inherited disorders · Match recipients of live organs from donors, making transplants more successful · Forensic evidence · Immigration evidence and paternity evidence · Solve crimes (Forensic science) · Identify an individual, individuals family, and to identify a body · Breeding animals, conserving nature and understanding evolutionary process By R.R 2012
DNA is important because of its tremendous discriminating power and stability. Following are the role of DNA in forensic science. - It is used for successful resolution of many crimes. - To identify potential suspects who’s DNA may match evidence left at crime scenes. - To exonerate persons wrongly accused of crimes. - It helps to identify crime and catastrophe victims. - To establish paternity and other family relationships. - It helps to identify endangered and protected species as an aid to wildlife officials (could be used for prosecuting poachers). - To detect bacteria and other organisms that may pollute air, water, soil, and food - It helps in match organ donors with recipients in transplant programs. - To determine pedigree for seed or livestock breeds. - To authenticate consumables such as caviar and wine.
