WebDuring karyokinesis the nuclear membrane disappears. Nuclear membrane starts disappearing at the start of mitosis and by the late prophase it disappears completely along with the major cell organelles. The nuclear membrane disappears presumably to allow more space for karyokinesis and proper separation of chromatids.

"WebKaryokinesis includes four phases - prophase, metaphase, anaphase and telophase. During prophase, the cell has a single nucleus and its nuclear envelope disappears. Later the nucleus divides into two. Hence, during telophase, the cell has two newly formed nuclei. A new nuclear envelope develops around the two newly formed nuclei.
