Question

The nuclear envelope disappears and reappears respectively during ________.

• A. telophase and metaphase
• B. telophase and prophase
• C. prophase and telophase
• D. prophase and anaphase

Answer 1

The correct option is C prophase and telophase

During cell division, there is division of duplicated genetic material (karyokinesis) followed by divison of cytoplasm (cytokinesis).

Karyokinesis 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.
