| | Ternary and quaternary fission |
 | | Finally, let us stress that beyond this specific problem of angular momentum, ternary fission continues to be not merely a curious peripheral-aspect of fission but, as shown in the present survey, is a precious source of information on the complex, and in many respects still puzzling, fission process as a whole. | | | According to theory the angular distributions of fragments are determined by the wave functions describing the transition states of the saddle point. | | | A more delicate question is at what stage of the fission process is the decision taken to emit an |

| | However, if there are further stages of binary fission within each generation in some radiolaria (as suggested previously in the literature and reported further here), this would permit additional stages of asexual proliferation of the radiolaria without swarmer production. | | | Paired shells observed in other colonoial radiolaria vary in geometry from two hemispherical shells fused at a common mid point to pairs of shells connected only by spines or an isthmus (e.g., | | | Likewise, as additional researchers examine plankton samples and living radiolaria in culture, any evidence of binary fission would be especially helpful to further document its occurrence in extant species. |

But when more realistic conditions were added, one by one, the results did not always support the fission hypothesis. |

| | Since prokaryotes lack a cell nucleus and various other organelles common to eukaryotic cells, they have the single replicated chromosome move to one end of the cell and "asexually" replicate, hence the term "fission". | | | These archaic cells reproduce simply by replicating their single chromosome into a duplicate ring and then dividing the cell into two distinct "daughter cells". | | | The cell replication of prokaryotic cells is known as binary fission. |
