As long as people have been trying to solve crimes, forensic science has been involved in one form or another. Whether it is deductive reasoning or modern science, evidence must be processed and understood in order to accurately describe what really happened. Forensic science is the use of science in a legal aspect (“forensics”), meaning that the findings must be presented to the court at the time of trial. Most often, these cases will involve a murder and conviction of the alleged murderer as the processed evidence is presented against them. Evidence is processed using different types of methods and techniques, and these methods and techniques have become increasingly dependent on technology over the past two decades. Forensic science and its methods have advanced through the production of biotechnology, facial reconstruction, carbon dating, ballistic science, and emerging technologies. Over the past half century, biotechnology, the creation of technologies involved in biological sciences, has changed the way forensic science uses DNA to solve crimes ("Biotechnology Used to Solve Crimes"). According to "DNA in Forensic Science", approximately half of all criminal cases today involve DNA evidence and the need to process it using biotechnology or DNA technology (Vitug). Biotechnology has created several different types of DNA technology that forensic scientists can now use to process DNA evidence. One of these methods includes PCR or polymerase chain reaction. This method is mainly used on small amounts of DNA in order to amplify it into a more manageable amount, which can then be used in one of the other types of DNA technology, namely DNA fingerprinting (Vitug ). As noted in "DNA Fi...... middle of paper ......logy, it appears that evidence becomes easier to process as new information is collected and new databases appear . Forensic science has exploited technological advances in order to develop new, more reliable methods of solving crime. Over the past half century, biotechnology has enabled the creation of DNA technology and bioinformatics, with genetic evidence now being presented in court more than in previous years. Other forensic methods have also advanced as new information has emerged and databases have been created, allowing for faster, easier and more efficient identification of evidence. Just as the technology we use every day is constantly evolving, the technology used in forensics is also evolving, allowing the emergence of new methods, techniques and information important to the crime solving world of police stations and agencies. government agencies like the FBI..
