During the G2 phase of interphase, the nuclear membrane increases its surface area and doubles its number of nuclear pore complexes. In eukaryotes such as yeast which undergo closed mitosis, the nuclear membrane stays intact during cell division. The spindle fibers either form within the membrane, or penetrate it without tearing it apart. In other eukaryotes (animals as well as plants), the nu… Webcharacteristics during mitotic nuclear envelope breakdown and reassembly.9,10 In mammals, the B-type lamins B1, B2 and B3 are encoded by two genes, LMNB1 and LMNB2,14-17 whereas all A-type lamins, the lamins A, AD10, C, and C2, are isoforms expressed from the single LMNA gene.14-17 While at least one B-type lamin seems to …
