During mitosis, the breakdown of the nuclear envelope depends on the disassembly of lamin filaments that form a meshwork supporting the membrane.  How is that breakdown accomplished?

#Unit 2. Cellular Organization

  1. Phosphorylation of nuclear lamins by a cyclin-dependent kinase active in early mitosis induces their disassembly.

  2. Dephosphorylation of nuclear lamins by a cyclin-dependent kinase active in early mitosis induces their disassembly.

  3. Dephosphorylation of nuclear lamins by a cdc14 active in early mitosis induces their disassembly.

  4. Phosphorylation of nuclear lamins by a CAK kinase active in early mitosis induces their disassembly.
