compare and contrast prokaryotic and eukaryotic cells

On the other hand, the active uptake of exogenous DNA, which is general in bacteria, was no longer essential in the genome organization of eukaryotes. As a consequence, a considerable increase has occurred in the size and complexity of eukaryotic genomes, providing the genetic basis for most of the further evolutionary changes in cellular complexity. The novel energy metabolism made it possible for the nucleotide synthetic apparatus of cells to be no longer limited by subsaturation with substrates and catalytic components.

Therefore, the intracellular compartmentalization of the energy-converting metabolism that was bound originally to the plasma membrane appears to be the key innovation towards eukaryotic genome and cellular organization. Because they house nuclei and other compartments or organelles that perform specific tasks, eukaryotic cells. This so–called symbiotic association hypothesis states that eukaryotes emerged when some ancient anaerobic archaebacteria (hosts) engulfed respiring αproteobacteria (symbionts), which evolved into the first energy–producing organelles. Compare and contrast Eukaryotic and Prokaryotic cells Eukaryotic cells: Eukaryotic cells contain a prominent, roughly spherical, membrane enclosed body called the nucleus, which houses DNA and the cell’s hereditary material. In contrast, it was recently proposed that the first complex cells, which were actually proto–eukaryotes, arose simultaneously with the acquisition of mitochondria. Eukaryotes have long been thought to have arisen by evolving a nucleus, endomembrane, and cytoskeleton.
