In the early 1950s, according to Allan and Lutz, the understanding of cancer could be summarized by the following statement: "Cancer cells are cells that have reverted to more primitive cells that behave less like eukaryotic cells and more like prokaryotic cells
As opposed to prokaryotic cells
in which pigment molecules are attached to peripheral membranes of the cell, the chloroplast represents highly organized arrangements of the chlorophyll, and the other pigment molecules are arranged in specific double membrane layers called thylakoids.
Flow cytometry (FCM), a powerful technique for the rapid characterization of cell populations, has been used widely to study prokaryotic cells
in different environments (Garcia-Ochoa et al.
International contributors to a dozen chapters examine telomeres' properties, replication strategies, and roles--perhaps as "double agents"--in the evolution of the genome from prokaryotic cells
(those without nuclei), and tumor expression/suppression.

FtsZ and the division of prokaryotic cells
By comparing the difference in sequences of homologous genes encoding ribosomal RNA (16S rRNA genes from prokaryotic cells
and 18S rRNA from eukaryotic cells) we can measure the evolutionary distance between species of organisms.
, which are represented by the eubacteria and archaea, contain precious little internal compartmentalization and have transcriptionally coupled translation, whereas eukaryotic cells, which compose plants, fungi, algae, animals, and a widely diverse group of unicellular protists, are equipped with a large cadre of intracellular compartments that are functionally specialized for specific intracellular tasks.
