Entry from US English dictionary
1Situated in or affecting parts of a cell outside the nucleus.
- Previous micromechanical studies of isolated nuclei have reported that nuclei are significantly stiffer than the extranuclear, cytoplasmic space of the cell.
- One such mechanism is extranuclear inheritance, which involves no physical change in the cell's genome, though it may involve changes in a heritable pattern of protein expression as in the following example.
- If, on the other hand, CI is caused by modification of extranuclear paternal factors, these white-eyed uniparental daughters will not be seen - they instead will die as embryos.
