Scientists have developed DNA computers: will future programmers "write" code with test tubes? Nowadays, we can't live or work without the help of computer However, with the advent of the era of big data, the parallel computing speed and storage capacity of electronic computing are facing development bottlenecks, and scientists began to find new computing media Recently, scientists have developed a widely programmable DNA computer, which is expected to complete multiple computing tasks Unlike electronic computing, DNA computing belongs to "wet experiment", that is, most of the operations are carried out in liquid In the DNA computing environment, to read data is not as convenient as an electronic computer, to look at an electronic screen, but to obtain the results by means of gel electrophoresis, fluorescence imaging, atomic force microscopy and transmission electron microscopy At present, DNA computing technology is still a long way to go, maybe 20 years Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-05 / 15 / content_ HTM?
