Sharing of components during the evolution of meiosis and mitosis

On the view that meiosis arose from bacterial transformation, during the early evolution of eukaryotes, mitosis and meiosis could have evolved in parallel, with both processes using common molecular components. On this view, mitosis evolved from the molecular machinery used by bacteria for DNA replication and segregation, and meiosis evolved from the bacterial sexual process of transformation, but meiosis also made use of the evolving molecular machinery for DNA replication and segregation.
