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.
Forensic DNA analysis can be a useful tool in aiding forensic identification because DNA is found in almost all cells of our bodies except mature red blood cells. Deoxyribonucleic acid is located in two different places of the cell, the nucleus; which is inherited from both parents, and the mitochondria; inherited maternally.
Investigative genetic genealogy, also known as forensic genetic genealogy, is the emerging practice of utilizing genetic information from direct-to-consumer companies for identifying suspects or victims in criminal cases. [1]
Developed in 1991, [10] DQ alpha testing was the first forensic DNA technique that utilized the polymerase chain reaction. [11] This technique allowed for the use of far fewer cells than RFLP analysis making it more useful for crime scenes that did not have the large amounts of DNA material that was previously required.

This article focuses on medico-criminal entomology and how DNA is analyzed with various blood-feeding insects. Forensic entomology can be an important aspect for law enforcement. With the magnitude of information that can be gathered, investigators can more accurately determine time of death, location, how long a body has been in a specific ...
DNA methylation is a common epigenetic mark being studied as potential evidence in forensic science. [5] [6] Unlike DNA, realistic DNA methylation is less likely be planted at crime scenes.> [6] Current methods to fabricate DNA usually exclude important methylation marks found in biological tissues making this a way to confirm the identity of an individual when evidence is being assessed.
Bloodstain pattern analysis (BPA) is a forensic discipline focused on analyzing bloodstains left at known, or suspected crime scenes through visual pattern recognition and physics-based assessments. This is done with the purpose of drawing inferences about the nature, timing and other details of the crime. [ 1 ]
