For 10 points, name this double lipid bilayer that
 surrounds the nucleus.
Nesprin 2 Giant helps to organize and maintain this structure. The LEM domain is associated with
 proteins in this location. Other important proteins here include emerin and MAN1 which are found in its
 inner region. It is bridged by Nup210 and movement through that bridging substructure is controlled by
 proteins like RAN and importin. One disease caused alterations to this structure is progeria which results
 from mutations in its intermediate filaments called lamins. This structure contains pores and is contiguous
 with the ER. It is disassembled near the end of prophase. For 10 points, name this double lipid bilayer that
 surrounds the nucleus.
