Document Summary
Oxygen atmosphere, single celled aerobic organisms (appearance of the irst eukaryote) Muliple linear chromosomes and diploidy variaion. *linear: allow muliple start points (26 pair of chromosomes), instead of going around the circular genome slowly. **diploidy: allow the alternate chain/pair to take over if one of them is damaged. Specialize in dna replicaion and message producion. In fold of outer plasma membrane to increase s. a. for the cell. The in folding may have extended to the point from two sides, end up surrounding the nuclear material. End up with 2 phospholipid bilayer (do not need ribosome, trna ) 3rd compartment, the space created by the in folding, provide a space for moving things around the cell, without travelling in the cytoplasm (without disturbing the funcion of the cell) Mitochondria formaion is a successful innovaive event that every eukaryote cell decent from that cell. First understanding on the evoluion of diversity of the planet:
