World’s smallest tape recorder has been built inside a living bacteria
New York: Experts hacked the immune system inside a bacterium and have placed a controlled tape recorder in it, which makes note of changes in the surrounding and stamp the time which is called ‘time stamping’. Tape recorder records these changes on DNA. In this way, the timely monitoring of health and pollution in any biological environment might be reviewed instantly. World’s smallest tape recorder has been built inside a living bacteria.
World’s smallest tape recorder has been built inside a living bacteria. Experts in Colombia University Medical Center of US have changed the genes in Escherichia coli. Bacterium through CRISPR-CAS system. This bacterium can naturally remember the genetic information of the bacterium virus. Senior biologists working on it say that CRISPR- CAS system is a natural memory device and information can be stored in it. It has been named as a revolutionary technology and now it has become an important tool for genetic engineering. Bacteria remembers the virus attack and deals against the attack next time.
Through CRISPR- CAS technology, experts are also editing genes and it is used worldwide to work on HIV and cancer therapy. By e-coli bacteria, experts first took the task of converting DNA into small pieces (Plasmid) and then performed two different tasks. A plasma was used as timekeeper to find out time which has noted and copied the breaks in the bacterium genome while altering the other plasma slightly, it was made able to identify external signals. Thus, the bacterial breakthroughs can be seen for observing when it has received an external signal.
Similarly, this bacteria can note activity in a patient’s body, such as virus attacks or any other and can work like a recorder. Such bacteria can enter the patient’s body, record the digestive gut and make the treatment of the patient possible.
