Forensic biology is the application of biological principles and techniques in the investigation of criminal and civil cases. [1] [2]Forensic biology is primarily concerned with analyzing biological and serological evidence in order to obtain a DNA profile, which aids law enforcement in the identification of potential suspects or unidentified remains.
Forensic science, also known as criminalistics, [1] is the application of science principles and methods to support legal decision-making in matters of criminal and civil law. During criminal investigation in particular, it is governed by the legal standards of admissible evidence and criminal procedure.
There are three general categories in which forensic science uses trace evidence. It can be used for investigative aids, associative evidence, and in-scene reconstructions. [ 3 ] In terms of investigative aids, trace evidence can provide information to determine the origin of a sample and determine the manufacture date of the material, all of ...
In a paper published in the journal Forensic Science International: Genetics, the Israeli researchers demonstrated that it is possible to manufacture DNA in a laboratory, thus falsifying DNA evidence. The scientists fabricated saliva and blood samples, which originally contained DNA from a person other than the supposed donor of the blood and ...
The US government's own Combined DNA Index System (CODIS) database is composed of forensic evidence assessable to local, state, and federal law enforcement officials. This database consists of genetic profiles of approximately 18 million different people, however these are limited to DNA samples from convicted felons and arrestees. [ 26 ]
Forensic limnology – analysis of evidence collected from crime scenes in or around fresh water sources. Examination of biological organisms, in particular, diatoms, can be useful in connecting suspects with victims. Forensic linguistics – deals with issues in the legal system that requires linguistic expertise.
Forensic entomology is a branch of applied entomology that uses insects found on corpses or elsewhere around crime scenes in the interest of forensic science. This includes studying the types of insects commonly found on cadavers , their life cycles, their presence in different environments, and how insect assemblages change with decomposition .
Forensic identification is the application of forensic science, or "forensics", and technology to identify specific objects from the trace evidence they leave, often at a crime scene or the scene of an accident. Forensic means "for the courts".
