The nuclear envelope re-forms

Verified step by step guidance
1
Understand that mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.
Recognize that mitosis is divided into several phases: prophase, metaphase, anaphase, and telophase.
During prophase, the chromatin fibers condense into discrete chromosomes that become visible under a light microscope.
In prophase, the mitotic spindle begins to form, which is crucial for the later separation of sister chromatids.
Note that the nuclear envelope does not re-form during prophase; instead, it begins to break down, allowing spindle fibers to interact with chromosomes.
