DNA can be the data storage but also the highly secured key to data. 

The new DNA testers that require only one or two cells can offer a new way to store data in the ultra-secure form. The DNA can store in the system, what is looking like a regular USB stick. The storage can be the glass plate where the DNA is stored. Or actually, the DNA that contains the data can store in bacteria that are between the glass plates.

The system might have regular magnetic data storage. But also the secret locker where the data is stored in the DNA. The computer can read the memory stick can by using a regular USB station if the person wants to use the magnetic data. But if a person wants to use the data that is stored in DNA. 

That thing can do by using the special station that pulls the glass out, and then the system can release the data by using a laser or some other system. If the access code that the user gives is wrong, that thing can cause that laser will destroy the data. 

For the DNA sample is needed a couple of cells. And maybe somewhere in the future, the DNA can replace the access codes. The system just takes a couple of cells, and then the DNA will open the access to the computer. If the DNA test and verification are fast and trustable the DNA can use to authenticate access to the secured networks. The system takes only a couple of cells from the skin and then verify access to the system.

The manipulation of the DNA allows to program memories in the bacteria by rewriting their DNA. 

The DNA (and RNA) are controlling every single operation that bacteria are doing. If the DNA of the bacteria is changed it can turn to antibiotics factory or cannibal bacteria. By using genetic engineering the bacteria can turn into cloned immune cells or they can use to replace the destroyed tissues. DNA is like a chemical computer program. If the DNA can cut and connect to certain points, the bacteria can make the operations in sequences. 

The DNA manipulated bacteria might have three sequences in its operations. DNA is like a chemical computer program, where can involve missions for bacteria. In the next example, genetically engineered bacteria are used to fix the tissue damage. 

For making this thing in the real world the bacteria is needed three sequences of the DNA. Those sequences are controlling each sequence of the mission of those bacteria. 

1) Bacteria is searching the wounded tissue

2) Bacteria is cleaning the area

3) Bacteria turns to tissue cells.

At first, the bacteria can search for destroyed tissue. And when the bacteria is finding the tissue, the next sequence of the DNA will make it destroy the hostile cells. In the final sequence, the DNA can turn those bacteria into new tissue cells. 

And this thing can be one example of how genetic engineering can use for serving mankind. By using genetic manipulation and trans-genetic bacteria is possible to clone neurons or anything else. The bacteria can destroy the oil and other pollution. They can neutralize explosives by removing the catalysator from the chemical structures.
