Bioengineers at Harvard have learned to read and write information from DNA molecules, like the stick. Scientists were able to write an e-book on the DNA of 5.27 megabytes, including 11 pictures, 53426 words, and even Java-script. Experts believe that the future will not replace hard drives and USB flash drive is come the DNA molecule, which, despite its tiny size, can contain a huge amount of data.
In the DNA molecules of the information is recorded using a binary code consisting of guanine, cytosine, adenine and thymine. Harvard bioengineers recorded the first e-book chain codes in the form of ones and zeros. Then, using the lab equipment they brought a lot of short chains of DNA molecules containing the coded chain of signs.
All they got about 55 thousand of these fragments, each of which stores a particular piece of ciphertext. As such, the information can be stored for hundreds of years and contain a library of data. It can be stored as a liquid or solid salt.
Note that this was not the first attempt to write data to the DNA molecule. So, in 2010, Craig Venter and his colleagues first brought artificial cell and left her encrypted information about your name, personal web page, and also recorded a few quotes. Researchers from Canada, the U.S., Europe trying to write to the DNA not only text, but also other types of data, such as trademarks. Other scientists write in bacteria popular music. So it is quite likely that we will soon forget all about such traditional means of data storage as a disk or flash drive.
