The nucleus breaks apart and emits several particles.
Beyond point B, the Coulomb repulsion between the protons drives the nucleus into further elongation until at some point, S (the scission point), the nucleus breaks in two.
The compound nucleus breaks up just before gamete formation, and the minute individual nuclei undergo meiosis and wander to the elaborate tip structures, where they are released as uninucleate gametes.
When an atomic nucleus breaks apart, or undergoes fission, a far more disruptive process than ordinary radioactive decay, enormous amounts of energy, as well as several neutrons, are liberated.
Calculations suggested that the comet's nucleus broke up after a near collision with the giant planet Jupiter in July 1992 and predicted that the pieces would plunge into Jupiter's atmosphere about July 20 , 1994 unleashing an energy equivalent to roughly 100 million megatons of TNT.
This again is most probably attributed to the destruction of P63 receptors as a result of the nucleus break-down at high grades.
When the nucleus broke away from cell center, we observed an initial burst of actin polymerization at the cortex overlying the displaced nucleus.
As the nucleus breaks down (Gorjanacz et al., 2007), microtubules grow outward from the centrosomes and attach to the chromosomes and to the anterior and posterior cell cortex.
As the nucleus breaks down, there is an inflow of GFP-labeled molecules from the cytoplasm into the nuclear region and its fluorescent intensity increases.
For the briefest of moments, the nuclei break down into their constituent bits - particles called quarks and gluons - a state of matter that has not existed since a microsecond after the big bang that began the universe.
Nuclear fission is a mature though controversial energy technology where electricity is generated from the energy released when heavy nuclei break apart.
