Cell Reproduction: Mitosis - 11 Cytokinesis in Plant Cells Binary Fission – Cell Division in Prokaryotes The process of cell division in prokaryotes, is called binary fission. Bacteria have just one long continuous, or circular molecule of DNA. That, and the absence of a nucleus in the prokaryotic cell, account for a number of differences in the "mechanics" of the process. Special proteins attached to the DNA molecule facilitate the folding needed for the prokaryote's DNA molecule to fit within the cytoplasm of the cell. At the beginning of cell division, the single DNA molecule attaches to the plasma

Unformatted text preview: membrane at a site on the chromosome identified as the origin. The DNA is duplicated using a complex of enzymes (very similar to that of eukaryotes). While the DNA is being duplicated, the cell elongates by synthesizing new membrane and wall material between the two origin regions, separating the two DNA molecules. After a period of elongation plasma membrane is pulled inward, pinching off the two halves of the original cell. New cell wall material is also synthesized.
