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.

Famous quotes containing the words sharing, components and/or evolution:
“The meaning of the Street in all ways and at all times is the need for sharing life with others and the search for community.”
—Virginia Hamilton (b. 1936)
“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
“What we think of as our sensitivity is only the higher evolution of terror in a poor dumb beast. We suffer for nothing. Our own death wish is our only real tragedy.”
