Nucleosynthesis. Diagram illustration the creation of new elements by the alpha process. Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons (protons and neutrons) and nuclei. According to current theories, the first nuclei were formed a few minutes after the Big Bang, through nuclear reactions in a process ...
Nuclear fusion is a reaction in which two or more atomic nuclei, usually deuterium and tritium (hydrogen isotopes), combine to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or absorption of energy.
Fusion gene. In genetics, a fusion gene is a hybrid gene formed from two previously independent genes. It can occur as a result of translocation, interstitial deletion, or chromosomal inversion. Fusion genes have been found to be prevalent in all main types of human neoplasia. [1] The identification of these fusion genes play a prominent role ...
The primary impetus for NIF’s construction was the promise that fusion reactions ignited by the facility’s powerful lasers would yield data that would help the U.S. maintain its nuclear ...
If scientists can solve the remaining puzzle pieces behind these technologies, both nuclear fission and fusion are poised to have a big impact on the world’s energy reserves and green energy ...
Karyogamy is the final step in the process of fusing together two haploid eukaryotic cells, and refers specifically to the fusion of the two nuclei. Before karyogamy, each haploid cell has one complete copy of the organism's genome. In order for karyogamy to occur, the cell membrane and cytoplasm of each cell must fuse with the other in a ...
Mitochondrial fusion. Mitochondria are dynamic organelles with the ability to fuse and divide (fission), forming constantly changing tubular networks in most eukaryotic cells. These mitochondrial dynamics, first observed over a hundred years ago [1] are important for the health of the cell, and defects in dynamics lead to genetic disorders.
Cell fusion is an important cellular process in which several uninucleate cells (cells with a single nucleus) combine to form a multinucleate cell, known as a syncytium. Cell fusion occurs during differentiation of myoblasts, osteoclasts and trophoblasts, during embryogenesis, and morphogenesis. [1] Cell fusion is a necessary event in the ...
