A beta-stable nucleus may undergo other kinds of radioactive decay (alpha decay, for example).

Calculations in a quantum tunneling model show that such superheavy nuclei would undergo alpha decay within microseconds or less.

This megaspore becomes larger and the nucleus of it undergoes mitosis three times until there are eight nuclei.

It was found that the final nucleus undergoes spontaneous fission.

At the same time, each nucleus undergoes mitotic division to produce two daughter nuclei.

In Parkinson and Alzheimer diseases the nucleus undergoes degeneration.

These nuclei undergo karyogamy and meiosis upon germination of the spore.

If the monosporic pattern occurred, the single nucleus undergoes mitosis three times, producing an eight-nucleate cell.

During sexual reproduction, the nucleus undergoes multiple rounds of mitosis, forming many daughter nuclei all within one nuclear membrane.

Spontaneous fission can occur much more rapidly when the nucleus of an atom undergoes superdeformation.
