Viruses and the Genesis of Eukaryotes
These same properties are crucial to eukaryote cells with organelles and endosymbionts. The cellular membrane provides the boundary.
Eukaryotes make use of a number of self-assembling radially-symmetric proteins in the construction of their flagellum, cilium, mitotic spindles, centrioles, and cytoskeletons.
Viruses and Bacteria -- Flagellum explained how filamentous viruses evolve into flagella.
Mitosis in eukaryotes involves the self-assembling mitotic spindles piercing the nuclear membrane to connect with the chromosomes. Again, not much of a stretch for viral-derived proteins.
In eukaryotes it would seem likely that the spindles or their
progenitors were responsible for moving some DNA from organelles to
