Biohackers managed to introduce an informatic virus into a DNA chain

The human DNA is similar to a hard disk where all the information of our genetics is stored and that is conserved and replicated from generation to generation over time, so it is not surprising that biohackers have managed to intervene in the structure that keeps our history. Biohackers managed to intervene a human DNA chain with an informatic virus Before this hazana, what had been achieved with the DNA was to code it and then download it again to a computer. However, it is now possible for malware to also be stored in a DNA strand .But not to spread the panic yet, because this sounds much scarier than it really is. A malware is nothing more and nothing less than a virus designed to infect computers in order to cause damage to the user and, first of all, benefit the person who created the program.
