1. Prokaryote cells evolved first and gave rise to eukaryote cells.

2. Plant pathogenic bacteria are tiny prokaryote with the characteristic of rapid propagation.

3. Flagellum (pl. flagella) A whiplike extension of prokaryote cells, with a basal body at its base, whose beat causes locomotion of the cell.

4. Prokaryote (prokaryote) An organism whose genetic material (DNA) is not enclosed by membranes to form a nucleus but lies free in the cytoplasm.

5. Turgor The state, in a plant or prokaryote cell, in which the protoplast is exerting a pressure on the cell wall owing to the intake of water by osmosis.

6. It seems likely, then, that genes from distantly related prokaryotes are occasionally recombined.

7. Such cells may have evolved from a coming-together of prokaryotes.

7.

8. Plastids are essential organelles of plant cells and it is believed that plastids have arisen from an endosymbiotic event between a protoeukaryote and a photosynthetic prokaryote.

9. The most fundamental dividing line between living organisms is that between prokaryote and eukaryote cells.

10. Signal peptides' structures and functions, signal sequence traps and the proteins expressions in prokaryote and eukaryote expression systems were illustrated in the article.

11. Mycoplasma pneumoniae is a range between viruses and bacteria, the smallest self-propagation prokaryote , is the cause of children and respiratory infections of SARS one of the main pathogens.

12. Serine hydroxymethyltransferase(SHMT) is widely distributed in nature, being found in prokaryote and eukaryote and catalyzes the reversible interconversion of serine and glycine.

13. This is the first time that genomes have been transferred between branches of life—from a prokaryote to eukaryote and back to a prokaryote.

14. Mycoplasmas are widespread in nature as conditional pathogen, which may be the unique prokaryote that can cohabit with eukaryote and interact permanently with mammalian cells.

15. Eukaryote --- A unicellular or multicellular organism in which the cells have a nucleus with a nuclear membrane and other specialized characteristics. See also prokaryote.

16. The family of zinc finger proteins is an important member of transcription factors which exists widely in prokaryote and eukaryote.
