Splet2.1: Disintegration of nuclear envelope starts in the pro-metaphase and is absent during metaphase and anaphase. Nuclear envelope reappears in the telophase. 2.2: Throughout mitosis, DNA is in condensed form. It is uncondensed only during interphase (G1-S phase) for DNA replication. SpletThe nuclear envelope is also called nuclear membrane. It is made up of two lipid bilayer membranes. The nuclear membrane is present in both the plant and animal cells. Cells carry out a multitude of functions such as protein building, conversion of molecules into energy and elimination of unnecessary products.

"SpletDuring prophase, the "first phase," the nuclear envelope starts to dissociate into small vesicles. The membranous organelles (such as the Golgi apparatus and endoplasmic reticulum) fragment and disperse toward the periphery of the cell.

SpletThe nuclear envelope (NE) represents the boundary of the interphase nucleus. It is composted of two morphologically distinct parallel membranes, the inner and outer nuclear membranes, enclosing a perinuclear space (Figure 1 ).
