The DNA otherwise known as genetic coding is permeated throughout your body used to create the characteristics that make living things themselves. Genetic fingerprints can be used to identify a person at a crime scene or if there is a missing person looking at unique patterns throughout their DNA. DNA profiling is a method used by forensic staff to compare the profiles of criminals and suspects with those of DNA left on a crime scene. One theory was retained by a French police investigator implying the thought that no matter the crime, there will always be evidence found at the scene of the crime. This principle can be used to discover the author indefinitely.

A DNA profile consists of cell samples, these samples can be found in all parts of the body eg skin, blood cells or even hair. DNA can be extracted from these cells before being amplified. By using gel electrophoresis, forensic scientists are able to extract the specific coding hidden inside the DNA to show their bars in what is unique to each person, making it quite easy to link the said DNA to that of the suspects or the victim, according to the crime.

Once the DNA sample has been brought back to the laboratory, forensic scientists can use methods to interpret who the DNA matches. With the use of technology, forensic scientists can develop a DNA profile in which can be used to locate and possibly arrest the criminal found guilty of the crime. The detectives compare the DNA found at the scene of the crime with that of the suspects and the victim for concise and direct execution. Once the DNA sample has been returned to the laboratory, scientists can use an electrophoresis gel to lure the DNA protons with a charge to understand the unique pattern of a person’s bars superimposed in their DNA .

One problem demonstrated when using DNA to convict criminals is that there are not always traces of DNA at the scene of the crime because it may have been removed by the criminal in which they had been left. There is the possibility of a natural disaster that could annihilate the entire crime scene before that of the judicial police can get their hands on the evidence. Finally, the last problem they may face is the fact that they rely too heavily on the use of DNA to link criminals to crimes committed as they frequently use it. Thanks to DNA analysis with electrophoresis, forensic scientists can detect that of the suspect, although there is a problem that there is the possibility that someone else’s DNA may be either at the scene of the crime if the person had met someone before they were shot.

The DNA was initially established by a Swiss psychological chemist Friedrich Miescher in which he had identified it as a nuclein found in the nucleus of white blood cells this discovery was later changed to deoxyribonucleic acid otherwise known as DNA. This discovery would change the way we use science to our advantage.

The murders of three prostitutes, 1990: Solved through DNA evidence.

This case was solved by the location of DNA evidence the judicial police were able to identify that Douglas Perry, the murderer, had since changed his sex. He was arrested in 2012 for possession of illegal firearms. The investigation of the three deaths was initiated in 2005 with DNA evidence sent in 2009 and submitted to a federal database that corresponded to Perry. Other evidence such as the underwear of the murdered girl inside her closet. Without the use of DNA, the case would never have been able to tie the crime to the murderer after he changed sex.

DNA has been used for medico-legal practices to effectively modify and evaluate a crime scene or otherwise to fully establish those who have been affected throughout the crime, including the victim, the suspect and other factors that may be included to solve any crime. One can use DNA to link murder to murderer (s) at any crime scene, this can be done using gel electrophoresis to attract protons with a positive charge to the gel to see the pattern of bars in which is unique to each person.The DNA otherwise known as genetic coding is permeated throughout your body used to create the characteristics that make living things themselves.
