New Technique Stores Data in BacteriaArtificial DNA with encoded information can be added to the genome of common bacteria, thus preserving the data. The technique was developed at Keio University Institute for Advanced Biosciences and Keio University Shonan Fujisawa Campus. If you think those USB flash memory "thumbdrives" are small, check this data storage out. According to researchers, up to 100 bits of data can be attached to each organism. Scientists successfully encoded and attached the phrase "e=mc2 1905" to the DNA of bacillus subtilis, a common soil bacteria. One early use for the technique would be to create special markers to identify legitimate versions of pharmaceuticals. However, the bacillus itself creates new copies of the data every time it reproduces itself, thus making it an ideal archival storage system. Bacillus subtilis also creates extra copies of the data, inserting it in different places in its genome, further safeguarding the data. That's "multiple backup copies" for those of you who have lost data in the past. The first time I read about this idea was in an excellent series of fantasy novels by Barbara Hambly. In her 1982 Darwath trilogy, she writes about how wizards of several thousand years ago succeeded in tying information to the DNA of selected individuals. In the story, several people from 1980's California find themselves transported across the Void to another planet and the Realm of Darwath. They face a deadly species of queerly magical beings - the Dark - who destroyed civilization thousands of years ago. Everything that was made of paper (like books and records) was burned to stave off attacks by the Dark. Tying memories to a few suitable bloodlines (DNA) was the only way to preserve a record (information) of that period that would endure. |

DNA
From Wikipedia, the free encyclopedia
Deoxyribonucleic acid, or DNA, is a nucleic acid molecule that contains the genetic instructions used in the development and functioning of all known living organisms. The main role of DNA is the long-term storage of information and it is often compared to a set of blueprints, since DNA contains the instructions needed to construct other components of cells, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.
Chemically, DNA is a long polymer of simple units called nucleotides, with a backbone made of sugars and phosphate atoms joined by ester bonds. Attached to each sugar is one of four types of molecules called bases. It is the sequence of these four bases along the backbone that encodes information. This information is read using the genetic code, which specifies the sequence of the amino acids within proteins. The code is read by copying stretches of DNA into the related nucleic acid RNA, in a process called transcription. Most of these RNA molecules are used to synthesize proteins, but others are used directly in structures such as ribosomes and spliceosomes.
Within cells, DNA is organized into structures called chromosomes and the set of chromosomes within a cell make up a genome. These chromosomes are duplicated before cells divide, in a process called DNA replication. Eukaryotic organisms such as animals, plants, and fungi store their DNA inside the cell nucleus, while in prokaryotes such as bacteria it is found in the cell's cytoplasm. Within the chromosomes, chromatin proteins such as histones compact and organize DNA, which helps control its interactions with other proteins and thereby control which genes are transcribed.

When the gel has hardened (polymerized), the tape is removed and the plates are placed in the ABI automated sequencing machine. Buffer trays at the top and bottom are installed so that electrical current can run through the gel.

Forensics
Forensic scientists can use DNA in blood, semen, skin, saliva or hair at a crime scene to identify a perpetrator. This process is called genetic fingerprinting, or more accurately, DNA profiling. In DNA profiling, the lengths of variable sections of repetitive DNA, such as short tandem repeats and minisatellites, are compared between people. This method is usually an extremely reliable technique for identifying a criminal.[113] However, identification can be complicated if the scene is contaminated with DNA from several people.[114] DNA profiling was developed in 1984 by British geneticist Sir Alec Jeffreys,[115] and first used in forensic science to convict Colin Pitchfork in the 1988 Enderby murders case.[116] People convicted of certain types of crimes may be required to provide a sample of DNA for a database. This has helped investigators solve old cases where only a DNA sample was obtained from the scene. DNA profiling can also be used to identify victims of mass casualty incidents.[117
