Eukaryotic cells shared a more recent common ancestor with Archaeans than with bacterial cells. ... Prokaryotes undergo a process that produces cells that are identical. This process is called. binary fission. 30. The prokaryotic DNA is located in the. nucleoid region.
Prokaryotes such as bacteria propagate by binary fission. For unicellular organisms, cell division is the only method to produce new individuals. In both prokaryotic and eukaryotic cells, the outcome of cell reproduction is a pair of daughter cells that are genetically identical to the parent cell.
Sister chromatids are the two identical halves of a single replicated eukaryotic chromosome. They are joined at the centromere(see diagram at right) and are genetically identical because, during interphase, they are produced from the two complementary strands of a single duplex DNA molecule (more about replication >>).
In order to make new cells, all cells must undergo cell division, or cell reproduction. In prokaryotes , single-celled organisms without a nucleus, cell division occurs by binary fission .
