The Combined DNA Index System (CODIS) is the United States national DNA database created and maintained by the Federal Bureau of Investigation.CODIS consists of three levels of information; Local DNA Index Systems (LDIS) where DNA profiles originate, State DNA Index Systems (SDIS) which allows for laboratories within states to share information, and the National DNA Index System (NDIS) which ...
As of March 18 [3] 2016 one Rapid DNA instrument was approved by the FBI for submission of samples to NDIS/CODIS without manual review: the DNAScan manufactured by NetBio in Waltham, MA. Effective January 1, 2017, the DNAScan lost its approved status as CODIS-participating labs are required to include the 20 CODIS Core Loci.
Four novel alternative genetic codes were discovered in bacterial genomes by Shulgina and Eddy using their codon assignment software Codetta, and validated by analysis of tRNA anticodons and identity elements; [3] these codes are not currently adopted at NCBI, but are numbered here 34-37, and specified in the table below. The standard code
A DNA database or DNA databank is a database of DNA profiles which can be used in the analysis of genetic diseases, genetic fingerprinting for criminology, or genetic genealogy. DNA databases may be public or private, the largest ones being national DNA databases. DNA databases are often employed in forensic investigations.
The Checking Integrated Circuit (CIC) is a lockout chip designed by Nintendo for the Nintendo Entertainment System (NES) video game console in 1985; the chip is part of a system known as 10NES, in which a key (which is stored in the game) is used by the lock (stored in the console) to both check if the game is authentic, and if the game is the ...
Now that many genomes have been sequenced, VNTRs have become essential to forensic crime investigations, via DNA fingerprinting and the CODIS database. When removed from surrounding DNA by the PCR or RFLP methods, and their size determined by gel electrophoresis or Southern blotting, they produce a pattern of bands unique to each individual ...
A microsatellite is a tract of repetitive DNA in which certain DNA motifs (ranging in length from one to six or more base pairs) are repeated, typically 5–50 times. [1] [2] Microsatellites occur at thousands of locations within an organism's genome. They have a higher mutation rate than other areas of DNA [3] leading to high genetic diversity.
The 3′-untranslated region (3′-UTR) is a region of the DNA which is transcribed into mRNA and becomes the 3′-end of the message, but which does not contain protein coding sequence. Everything between the stop codon and the polyA tail is considered to be 3′-untranslated. The 3′-untranslated region may affect the translation efficiency ...
