Nuclear Energy
control system of the cellcontains DNA [in the chromosomes]has nucleolussends instructions to the rest of the cellduring process of mitosis, the nucleus splits to form nuclei...the nucleus is like a brain.....it controls everything.....=]
Yeast can reproduce in two ways. One is when a single cell splits into two child cells. This also occurs in bacterial. The other way is when an outgrowth is formed, the nucleus divides and the new nucleus migrates to this outgrowth and splits off.
A machine that smashes atoms together in order to observe what the universe may have looked like seconds after the "Big Bang" is called a particle accelerator. who ever is asking this is wondering what its CALLED not what it does! btw: Particle accelerator.
When a cell divides it produces two new cells, Daughter Cells. These are identicle to the parent cell in every way exept size (Nb not true for the first divisions of cell that will become a multicellular organism). To separate, the parent cell must replicate all its DNA so that both the daughters have a full Genetic Code. The DNA is stored within a nucleus (in Eukaryotes, not bacteria etc) and just before the cell splits there are two nuclei in it. These nuclei move through the cytoplasm to the most separate points in the cell, stretching the cell out into a an oval shape. Once this has happend this has happend the middle of the cell shrinks until the two sides meat. Think of it like having a long sausage shaped balloon with a peice of string looped around it. If you pull the string tighter the balloon shrkins in the middle. When the two sides of the parent cell meat they Fuse forming the two new daughter cells.
In prophase I, doubled homologous chromosomes group together to form a tetrad.
nuclear fusion
In both cases energy is released through annihilation of mass
Fusion. When a nucleus splits into two or more fragments this is called Fission.
Nuclear Fission
The energy of nuclear power comes from the binding energy that holds an atomic nucleus together. A heavy nucleus, usually uranium-235, splits into two smaller nuclei and releases three neutrons. These new nuclei have less binding energy than the original, and the excess energy is released as heat.
It is true that a uranium nucleus splits in the nuclear fission of uranium.
Nuclear fission.
Nuclear fission is nuclear reaction in which nucleus of an atom , usually a heavy element, splits into smaller parts i.e. lighter nuclei . Free neutrons and photons are produced along with release of large amount of energy.
fission: nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller partsfusion: nuclear fusion is the process by which two or more atomic nuclei join together "fuse"

Cytokinesis is not the stage of mitosis. It is the process in which cytoplasm of cell splits while mitosis is a process in which nucleus of cell is splitted into two daughter nuclei.
Nuclear fusion:Two or more atomic nuclei join together to form a single nucleus.Energy is released.Nuclear fission:One atomic nucleus splits into two or more separate nuclei, plus other fragments.Energy is released.
