That's correct! The formation of a new nuclear membrane around chromosomes is a key step in telophase, the final stage of mitosis (and meiosis). Here's what happens:

* Chromosomes Decondense: After the chromosomes are pulled to opposite poles of the cell, they start to uncoil and relax, becoming less condensed.

* Nuclear Envelope Formation: The nuclear envelope, which was broken down during prophase, reforms around each set of chromosomes. This happens because fragments of the old nuclear envelope, along with other membrane components, assemble around the chromosomes.

* Nucleolus Reappears: The nucleolus, which was also disassembled during prophase, reappears within the newly formed nucleus.

This process results in two distinct nuclei, each containing a complete set of chromosomes. This marks the end of nuclear division. The cell then proceeds to complete cytokinesis, the division of the cytoplasm, leading to the formation of two daughter cells.
