The nuclear membrane breaks down during prophase, while the Deoxyribonucleic Acid (DNA)
The nuclear membrane must break down to allow the chromosomes to be pulled apart and away from the area of the former nucleus towards the pole where the daughter cell will be formed. If the nuclear membrane did not break down the spindle fibers would not be able to reach the chromosomes and they would not be moved towards opposite poles of the cell.
when parts of chromosomes are broken off and lost during mitosis the results is a chromosomal mutation
Surgery for a broken eardrum, or tympanic membrane perforation, can be beneficial in certain cases, particularly when the tear is large, does not heal on its own, or leads to recurrent infections. The procedure, called tympanoplasty, aims to repair the eardrum and restore normal hearing. However, many small perforations can heal naturally without surgical intervention. The decision for surgery depends on the specific circumstances and the patient's overall health.

An egg
The nuclear envelope and nucleolus are broken down and absorbed during the prophase of mitosis. This prepares the cell for the division of its genetic material.
mitosis broken into 4 parts prophase metaphase anaphase and telophase
During prophase, the nuclear membrane breaks down, allowing the condensed chromosomes to be released into the cytoplasm. Additionally, the centrioles move to opposite poles of the cell and the spindle fibers begin to form.
The nuclear membrane is a double membrane surrounding the chromosomes of a eukaryotic cell.Together with associated structures, it is called the nuclear envelope. Perforations in the double membrane are termed pores; each is surrounded by a group of proteins collectively called the nuclear pore complex.The nuclear membrane defines the limit of the organelle called the nucleus. The membrane is broken into fragments during the first phase (prophase) of nuclear division. The fragments travel through the endoplasmic reticulum to the poles of the dividing cell, and are used to form the nuclear membranes of the daughter-cells.The pores permit large molecules to enter and leave the nucleus. For example, after transcription messenger RNA passes through a pore on its way to the cytoplasm for translation. And proteins synthesized in the cytoplasm enter the nucleus via pores before being incorporated in ribosome subunits being assembled in the nucleolus. These subunits subsequently leave the nucleus through the pores.

In a eukaryote cell the double walled nuclear membrane must be broken, or pierced to release the DNA into the cytoplasm and then the phospholipid bilayer would have to be breached next to release the DNA from this type cell A prokaryote cell would need both its cell wall and its plasma membrane breached to release the DNA from the cell.
Interphase and Mitosis.
Metaphase is identified in a cell undergoing mitosis by the alignment of chromosomes along the cell's equator. At this stage, the chromosomes are condensed and can be visualized under a microscope. Additionally, the nuclear envelope has already broken down in preparation for division.
