Viruses are the ultimate threat, but they are also the ultimate transmitters of genetic material.

Viruses are very important transmitters when the genomes are transmitted over the borders of species. The viruses are also a threat because they are hard to detect. Detection happens after some person or animal has been infected. 

 And the blood or tissue samples are involving antigens that are telling about virus infection. The thing is that viruses and especially artificial viruses are extremely powerful tools in bio and especially genetic engineering. 

Sometimes is researched the possibility to use the bacteriophages, the viruses that are destroying bacteria as the tool for controlling infections. The sad thing is that AIDS or HIV is one of the bacteriophages. In some scenarios, the genetically engineered HIV would use to destroy leukemia cells. The idea is that the specially engineered viruses would infect the cancer cells. 

And there is the possibility to make the viruses that can transmit their genomes only to cancer cells. The biggest problem is how to deny that viruses infect other than cancer cells. One of the solutions would create viruses which genomes can fit only to the ion pumps that exist only on the membrane of the cancer cells. But that requires the existence of that kind of ion pump. Genome therapy makes it possible to remove things like hereditary diseases. Nanotechnology makes it possible to create synthetic DNA. 

And that thing allows researchers to create things like artificial stem cells. Maybe in the future. The genetic code of every person's stem cells is stored in the computer. And if that person requires stem cells the system would clone those cells in the laboratory. In that case, every single person would have their stem cells laboratory waiting for their use. 

In some more futuristic ideas, the cells of every organ of the person would store in the laboratory. And if some organ would be damaged. The bioprinters would create a new organ for the person. This technology would turn the person immortal. The thing is that cloning human is possible. There is the possibility to change the genetic material from the nucleus of the fertilized eggs. In that process, the original genomes are pulled away. 

And the replacing genomes would inject into the cell. This thing is one of the most interesting things in genetic engineering. This kind of thing might be prohibited. But as you know the law is quite a weak thing. There is always the possibility to travel to countries where are no laws about this kind of thing. And the people who are working with this kind of thing might work remotely over the internet. They can control the robot arms by using remote-control tools.
