After fertilization, parental genomes are enclosed in two separate pronuclei. In Caenorhabditis elegans, and possibly other organisms, when the two pronuclei first meet, the parental genomes are separated by four pronuclear membranes. To understand how these membranes are breached to allow merging of parental genomes we used focused ion beam scanning electron microscopy (FIB-SEM) to study the architecture of the pronuclear membranes at nanometer-scale resolution.

- Many cells have a steady balance between the size of their nucleus and the rest of the cell, but scientists are unsure how this happens.
- When they stopped yeast cells from growing, the nucleus changed shape to become bilobed (like two blobs), with most DNA in one part and a structure called nucleolus in the other.
- This unique shape happens because of certain fats in the cells and depends on the cell's cycle actions, meaning the nucleus can grow differently without a change in its size compared to the cell.
