DNA ANALYSIS 2

DNA Analysis

DNA analysis is a forensic technique that evaluates collected genetic material from

relevant sources and uses the evaluation of those genetic materials to identify individuals who

are involved in a forensic investigation. The analysis of DNA can give important information

about evidence obtained from a crime scene. The results of the analysis can be entered as factual

evidence that can be used in court cases and helps in improving the effectiveness of the criminal

justice system due to the hard facts that it provides.

DNA analysis was first used as forensic evidence in the united kingdom in nineteen

eighty-six and it was provided by professor Jeffrey who linked the stains of semen samples

collected from a crime scene to the perpetrator of the crime and Kary Mullis who developed the

polymerase chain reaction that made DNA analysis comparatively easier than before (Calandro,

Reeder, & Cormier, 2005). The evidence was considered admissible if it was proved that the

scientific process of the analysis was generally accepted. The legitimacy of using DNA evidence

was challenged but ultimately accepted as long as it adhered to the standard set out by the

Supreme Court that required any DNA evidence to be accompanied by copies of the results and

reports and explanations for any actions that did not follow the proper regulations used for

handling and analyzing evidence. Finally, the federal bureau of investigations developed a

database that was a combined DNA index system which forced forensic analysts to adhere to the

proper standards (Calandro, Reeder, & Cormier, 2005).

The analysis of DNA follows a specific process. The first step of the analysis is to obtain

a sample of DNA from a person that is known. Usually, the cell on the cheeks in the inside of the

mouth is the sample collected by swabbing the cheeks or obtaining a blood sample, the samples

are then sent to the forensic laboratory. The next step involves systematically categorizing and

evaluating the samples that were collected. Following that the DNA is extracted from the sample
