Assembly of a nucleus-like structure during viral replication in bacteria

Viruses are very complex and amazing organisms, they have very good survival skills and always seem to find loopholes in nature.

I do think our cells grew more complex over time and incorporated more organelles. The mitochondria for example has its own bacterial DNA since our cells just adopted that bacteria as an organelle. The mitochondria gave our cells a way to 'breathe' and use oxygen to survive the changing atmosphere when the sulfur atmosphere changed to a nitrogen/oxygen based one in prehistoric times.

When we talk about our nucleus, we're essentially talking about our DNA. Our DNA is ovbiously different from a virus (RNA) but its true that both basically have the same job and have the same genetic drive to procreate and thus persevere, they just do it in very different ways. Our DNA chooses to build very complex organisms (humans) and have them mate to then exchange DNA to enrich the gene pool and further spread itself (the DNA). The virus' code (RNA) chooses to infiltrate other organisms and replicate in their cells to then further spread itself by multiplying itself insanely fast.

Viruses purposely allow for many mutations to occur in their replication to ensure that a very diverse gene pool is established. When our body finally creates a specific T memory cell for that virus, new viruses have already mutated so much that our body cant recognize it anymore.

I do think it is possible that these mechanisms and the organelles/nuclei with essentially the code for life in them may stem from the same source.
