The same thing what protects the Earth from bacteria and viruses, what is coming from other solar systems makes interstellar travel difficult

1) Can DNA survive in interstellar travel?

Can DNA or RNA survive in interstellar travel? I hope that the answer is "no", and the thing, what makes that thing very interesting is that the chemical conditions for that thing must be very stable. Then the oscillation of the atoms must be denied, and that thing requires the temperature, what is Zero Kelvin degrees. The thing is that the DNA or RNA molecule should go in the ice because of some reasons, and one is that somebody in the humanoid space station somebody flushes the toilet, and second is that the large mass of water would fly to space when the blast of the supernova hits the planet.

Then the size of the water mass must be high enough, that the genetic molecule would not get enough radiation and the extreme heat would not break the structure of the molecule. If the molecule would be frozen to the zero kelvin degrees, that thing makes possible that the DNA or RNA molecule could survive in the journey, which takes thousands or millions of years. But in this kind of thing, we must realize that the destruction of that molecule is the result of electromagnetic radiation.

So this is the reason, why interstellar travel is so complicated. Even if we would freeze the crew to temperature, what is zero kelvin, the electromagnetic radiation would destroy the DNA, and that means the crew would die. The next thing is taken from some science fiction book, where was written the scenario, that the crew of the craft will be

2) The destruction of DNA makes interstellar travel a very complicated thing, even in theory

And what kind of technology can make traveling to the other solar system possible? That thing requires highly sophisticated bio- and nanotechnology. The system could store the memories of the crew to the memory of the computer, as well as the structure of the DNA of those people would be stored. Then the bodies of those astronauts would be killed. If that thing is made someday in the future that requires the changes in the moral and ethics of the human race.

The cells that are stored in the spacecraft would be some bacteria or other things, which can easily crown in cultures. The craft would fly the interstellar journey with closed systems, and when the star will be close enough, the master computer and other systems would reopen, and the process of what mission is to colonize the planet will start.

The craft would travel thousands or millions of years to the targeted solar system, and then the system can start to create the DNA by using nanotechnology, which is unknown for us. Then those DNA bites will transfer to the cells, which is chosen for platforms. After that, the system would make the new crew in the chambers. Then the system would input the stored data to the brains of the crew. And of course, that data can be modified for serving the purpose.
