Investigating the Role of DNA as an Evidence in Criminal Justice System

DNA, or deoxyribonucleic acid, is the genetic blueprint found in humans and almost all other living things. It is consistently found in nearly all human body cells. The ability of DNA to replicate, or make identical copies of itself, is an essential property. By the 1980s, DNA analysis had become a valuable tool in resolving parentage disputes. DNA forensics has become integral to criminal investigations and judicial proceedings, providing a robust tool for establishing guilt or innocence with high accuracy. Testimonies from eyewitnesses are frequently untrustworthy, especially in high-stress circumstances as while a crime is being committed. Researchers found that memory distortions might cast doubt on eyewitness statements. On the other hand, DNA evidence is more difficult to disprove because it is based on scientific accuracy. Advancements in DNA technology have been pivotal in re-evaluating unsolved crimes and historical cases. Traditionally, DNA analysis is conducted in a laboratory setting, but Rapid DNA technology allows for the entire process to be performed within a specialized machine and computer system. By providing information at the outset of an investigation, Rapid DNA technology enhances crime-solving efforts and offers substantial benefits to the criminal justice system. Numerous studies have demonstrated that expanding DNA testing, generating faster DNA investigative leads, and ensuring the inclusion of all lawfully owed arrestee or convicted offender DNA profiles in databases are effective strategies for solving and preventing crimes, as well as deterring offenders
