A DNA database or DNA databank is a database of DNA data. A DNA database can be used in the analysis of genetic diseases, genetic fingerprinting for criminology, or genetic genealogy. DNA databases may be public or private.The United Kingdom National DNA Database (NDNAD); officially the UK National Criminal Intelligence DNA Database) is a national DNA Database that was set up in 1995. As of the end of 2005, it carried the profiles of around 3.1 million people. In March 2012 the database contained an estimated 5,950,612 individuals. The database, which grows by 30,000 samples each month, is populated by samples recovered from crime scenes and taken from police suspects and, in England and Wales, anyone arrested and detained at a police station.
Only patterns of short tandem repeats are stored in the NDNAD – not a person's full genomic sequence. Currently the ten loci of the SGM+ system are analysed, resulting in a string of 20 numbers, being two allele repeats from each of the ten loci. Amelogenin is used for a rapid test of a donor's sex.
However, individuals' skin or blood samples are also kept permanently linked to the database and can contain complete genetic information. Because DNA is inherited, the database can also be used to indirectly identify many others in the population related to a database subject. Stored samples can also degrade and become useless, particularly those taken with dry brushes and swabs.
The UK NDNAD is run by the Home Office, after transferring from the custodianship of the National Policing Improvement Agency (NPIA) on 1 October 2012. A major expansion to include all known active offenders was funded between April 2000 and March 2005 at a cost of over £300 million
Every State in the nation has a statutory provision for the establishment of a DNA database that allows for the collection of DNA profiles from offenders convicted of certain crimes. CODIS ("Combined DNA Index System") is a computer software program that enables State, local, and national law enforcement crime laboratories to compare DNA profiles electronically, thereby linking serial crimes to each other and identifying suspects by matching DNA profiles from crime scene evidence with profiles from convicted offenders and arrestees.The word "Index" in the CODIS name is not arbitrary. CODIS is designed to be a system of pointers to help United States crime laboratories compare and exchange DNA profiles. CODIS is not a criminal history database like the National Crime Information Center (NCIC). A record in the CODIS database, known as a CODIS profile, consists of a specimen identifier, an identifier for the laboratory responsible for the profile, and the results of the DNA analysis (known as the DNA profile). Other than the DNA profile, CODIS does not contain personal identifying information such as names, dates of birth, and social security numbers.In its original form, CODIS consisted of two indices: the Forensic Index and the Convicted Offender Index. The Forensic Index contains evidentiary profiles developed from biological material such as semen, saliva, or blood found at crime scenes. The Convicted Offender Index contains profiles of individuals convicted of crimes specified by State laws. All 50 states have passed DNA legislation authorizing the collection of DNA profiles from certain convicted offenders for submission to CODIS.
In recent years, CODIS has added new indices: the Arrestee Index, the Missing or Unidentified Persons Index, and the Missing Persons Reference Index. CODIS automatically searches across these indices for a potential match to aid criminal investigations of crimes from which unknown biological evidence has been recovered. It is important to note that if a hit is obtained from a convicted offender or arrestee sample, the hit is typically used as probable cause to obtain an additional DNA sample from that suspect so that the match can be confirmed by the crime laboratory before an arrest is made.The National DNA Index (NDIS) contains over 9,110,007 offender profiles ans 346,613 forensic profiles as of November 2010. Ultimately, the success of the the CODIS program will be measured by the crimes it helps to solve. CODIS' primary metric, the "Investigations Aided," tracks the number of criminal investigations where CODIS has added value to the investigative process. As of November 2010, CODIS has produced over 130,900 hits assisting in more than 127,600 investigations.The New York State DNA Databank became operational in August 1996, with the first hit, or match, linking an offender with DNA evidence from a crime scene in February 2000.
The Databank is part of the national Combined DNA Index System, known as CODIS. A searchable software program, CODIS provides for the sharing of DNA information among local, state and national databases.
The Federal Bureau of Investigation (FBI) serves as the national – NDIS – connection, linking New York State (SDIS) with other participating states. New York’s SDIS connection is in turn linked to eight local – LDIS – connections. This tiered approach allows for information sharing among federal, state and local agencies while allowing those agencies to operate their respective DNA database according to applicable federal and state laws and local policies
In India DNA Database :
The database remains an important tool for the police in solving crime. This report describes several case examples where the worst offenders have been caught and convicted following a database match. These examples are just a fraction of the serious crimes that the database continues to solve. We have transformed the DNA database from one that infringed the privacy of over a million innocent citizens to one that is proportionate and still effective. In this we hope also to have transformed it from a contentious system that was seen as a threat to our liberties, to one that enjoys wide public support as an essential tool to fight crime.In this base who are they missing People.It was used to find out the person Easily.
