DNA databases

In 1992, The United States, Federal Bureau of Investigation funded the Combined DNA Index System (CODIS). It is a computer system that stores DNA profiles created by federal, state, and local crime laboratories in the United States, with the ability to search the database in its entirety; it also helps agencies identify suspects of crime.

The origin of CODIS is attributed to the Scientific Working groups (SWG) that began in the late 80’s. SWG was backed by the FBI Laboratory which hosted several scientific meetings a year in Quantico, Virginia. Years later the FBI lead a project with six state and local crime laboratories to develop a software tool, to support each lab with DNA testing and sharing the DNA profiles with other crime laboratories .
In, 1994 the DNA Identification Act, authorized the FBI to operate CODIS and set national standards until recommendations were made by the DNA advisory board required under the act. Even though the Act was passed in 1994, CODIS did not become operational until 1998.

CODIS assist the crime laboratories to compare and exchange DNA profiles. A record in the Codis database, known as CODIS DNA profile, consists of an individuals DNA profile, along with a sample identifier and an identifier of the laboratory responsible for the profile. CODIS is not a criminal history database, like the National Crime Information Center (NCIC) and does not hold any personal information, like names, dates of birth, and social security number.

Originally, CODIS consisted of the Convicted Offender Index and the Forensic Index, but in recent years, the Arrestee Index, the Missing Persons Index, and the Missing Persons Reference Index have been added. The Convicted Offender Index contains profiles of individuals convicted of crimes. State law governs which specific crimes are eligible for CODIS. (All 50 states have passed DNA legislation authorizing the collection of DNA profiles from convicted offenders for submission to

    This program helps the Police Department in solving crimes through DNA samples, to identify suspects and solve cases. Thankfully, for this program, the Boston Police Department has been able to solve cold-cases from 50 years ago. It can be DNA from the actual crime offender, even from a cousin or nephew like in the case of Mary Sullivan. That wonderful molecule that makes us all unique, (except in the case of identical twins), can be vital evidence and used as a breakthrough to solve criminal cases. I will always believe in DNA and I think it speaks for itself!…

    In PBS, you learned about the molecular biology techniques that allow scientists to explore our DNA. PCR, Polymerase Chain Reaction, is the copy machine; the revolutionary process that allows scientists to replicate even the tiniest speck of DNA. Restriction endonucleases (enzymes) are the molecular scissors that can cut DNA in specific locations. Your specific code determines the number of times this set of scissors will snip and the number and size of DNA pieces that will be left behind. These pieces can then be separated and compared using the process of gel electrophoresis. As these fragments move, their varying lengths propel them through the gel at different speeds. Scientists can use these RFLPs, Restriction Fragment Length Polymorphisms, a set of DNA puzzle pieces unique to only you, to create a pattern called a DNA fingerprint. Similar to the unique…

    Deoxyribonucleic acid, also known as DNA contains genetic information and is found within the chromosome of human cells. After countless hours of research on thethis fairly new phenomenon it was Sir Alec Jeffereys of England who developed a technology that was based solely on DNA in 1985. DNA plays a major role in technology, it is used for identification, and it has been a leading source in identifying biological samples such as saliva, urine, blood, semen and hair. All of these samples have been extremely helpful with government, federal, state and even private agencies…

    The universal DNA database is important to the law enforcement agencies. The database will help the law enforcement agencies to identify suspects fast. When the universal data base is not used, it is very easy for a criminal to commit a crime and escape. The DNA universal database will improve the crime investigation thereby curbing the menace of criminals. When this takes effect, criminals might be extremely careful not to leave any trace that can help in getting their DNA for identification (Krimsky & Simoncelli, 2011). Nevertheless, the fear of being identified will result into a reduction in crime with many would be criminals staying away from crime. The implementation of the database will be a strong deterrent to first time offenders.…

    The use of DNA technology has increased the probability of finding the culprit and also prevents further crimes. Compared to the past, with DNA technology, today “more than twice as many suspects are[were] identified, twice as many suspects are[were] arrested and more than twice as many cases are accepted for prosecution” (Ritter, 2008). This is because of higher availability of DNA sources and uniqueness of DNA. Between two people, 99.9…
