DNA comes from the nuclei of cells. Any tissue or specimen containing cells or cellular material is likely to contain DNA.
The title of "forensic scientist" is a more general label, while forensic biologists focus specifically on living forensics. I would guess that forensic biology falls under the umbrella of forensic science.
There is a vast amount of chemical processes involved in forensics, it all depends on what it is you rare testing and what you need to find out. Techniques include: * Gas chromatography - separates a compound into is constituents i.e. fire accelerants * High performance liquid chromatography - also separates compounds, can be used for drug analysis * Polarography - can test for the presence of heavy metals in liquids * Raman Spectroscopy - can be used for ink and paint analysis * Fourier Transform Infrared Spectroscopy - can be used for anything from drug analysis to paint analysis * Flame Absorption Atomic Spectroscopy - can be used to detect metal ions in mixtures
The TV show "CSI: Crime Scene Investigation" welcomed us to the world of forensic medicine, showcasing how forensic evidence is used to solve crimes through detailed analysis and investigation of crime scenes.
Brand analysis is the procedure on comprehensively collecting qualitative and quantitative information from all available sources and assessing it to determine the state and perception of a particular brand. Brand analysis is used alongside competitor analysis and target analysis in order to make decisions which will maximise the financial benefit of the brand without sacrificing reputation.
The modern meaning of the word "forensic" is related to scientific techniques used for the investigation of crimes or legal matters, such as forensic science, forensic psychology, or forensic accounting. It often involves gathering and analyzing evidence to be used in a court of law.
In a forensic kit, ethanol is commonly used as a solvent for extracting DNA from samples or for cleansing surfaces to remove contaminants that could interfere with analysis. It is also used to preserve and store biological specimens for testing.
Biotechnology refers to the use of biological processes for industrial purposes, such as genetic manipulation. Forensic DNA analysis is an important part of biotechnology because it is used to match two DNA samples.
Forensic science was first used to solve a crime in the 19th century, with the development of techniques such as fingerprint analysis and toxicology. One of the earliest documented cases where forensic evidence was used to solve a crime was the murder investigation of John Toms in England in 1784.
No, forensic techniques can also be used in other areas such as archaeology, anthropology, and environmental science to analyze and interpret evidence. The principles of forensic science, such as evidence collection, analysis, and interpretation, can be applied to a variety of fields beyond criminal investigations.
The method commonly used for preparing DNA for forensic analysis is called polymerase chain reaction (PCR). PCR amplifies specific regions of DNA so that they can be analyzed in detail. This method allows for small amounts of DNA to be replicated, making it suitable for forensic samples with limited DNA material.
Other branches of forensic ballistics include firearms examination, toolmark analysis, gunshot residue analysis, and trajectory analysis. Firearms examination involves identifying firearms used in crimes, while toolmark analysis matches marks left on a surface to a specific tool. Gunshot residue analysis detects particles left behind on a suspect's hands after firing a gun, and trajectory analysis determines the path of a bullet through space.
Forensic hair analysis is used in criminal investigations to link suspects to crime scenes or victims. It can provide valuable evidence by identifying characteristics such as color, length, and damage to help establish connections between individuals and specific locations or events.
Two different methods used for collecting evidence are forensic analysis, which involves analyzing physical evidence like DNA, fingerprints, and fibers, and digital forensic analysis, which involves examining electronic devices like computers and mobile phones for evidence. Both methods are used to gather information and support investigations in various criminal cases.

Forensic scientists use a variety of techniques, such as DNA analysis, fingerprint analysis, ballistics, toxicology, and digital forensics, to analyze evidence from crime scenes. These techniques help them identify suspects, link evidence to a crime, and provide scientific support for criminal investigations.
DNA analysis - is the examination of blood to determine a match against a DNA database to identify a possible criminal. Blood spatter analysis - is the study of how blood has been left on surfaces - indicating the position of the victim - and the direction they were struck.
In forensic science, scientific principles and techniques are used to analyze physical evidence obtained from crime scenes, such as DNA analysis, fingerprint identification, and ballistics analysis. These scientific methods help investigators solve crimes by providing valuable information that can be used in court to support or refute a hypothesis about a crime.
