Cytoplasm
As mitosis winds down and the chromosomes reach their opposite poles of the cell, the poles of the spindle apparatus pull at the cell, elongating it. This elongation signals the nuclear envelopes to reassemble and surround the two clumps of chromosomes. In animal cells, a furrow appears around the cell that pinches it into two. In plant cells, a cell plate forms in the middle as the cell wall divides it into two.
The term "end" can refer to the end of a linear chromosome, where telomeres are located to protect the genetic information from degradation during cell division and prevent the loss of essential genes. Telophase is the final stage of mitosis when two daughter cells are formed, and the nuclear membrane re-forms around each set of chromosomes containing intact telomeres at their ends.
The X chromosome is generally larger and carries more genetic information compared to the Y chromosome. In the traditional system of organizing chromosomes by size, the X chromosome is placed in group C as it is larger, while the Y chromosome is smaller and simpler, so it is usually placed at the end of the fourth row.
A chromosome with a sub-terminal centromere has its centromere located towards one end of the chromosome rather than in the middle. This can affect the behavior of the chromosome during cell division and can impact genetic inheritance and variability.
The chromosome number at the end of meiosis is half of the parent cell

I thought they were acrocentric (centromere positioned so close to the end of the chromosome that the short arm of the chromosome is not visible) rather than telocentric (centromere located completely at the terminal end of the chromosome).

At the end of the telophase stage, there will be two nuclear membranes forming around each group of chromosomes. This is because the single nuclear envelope that broke down during prophase reforms during telophase to create two separate nuclei, each containing a complete set of chromosomes.

Chromosome inversion is a genetic rearrangement where a segment of a chromosome is reversed end to end. This can occur due to breaks in the chromosome followed by a reinsertion of the segment in the opposite orientation. Inversions can affect gene expression and may lead to genetic disorders or contribute to evolutionary changes. Inversion on chromosome 10 specifically can have various implications depending on the genes involved and the nature of the inversion.

Diploid chromosome number in standard laboratory mice (genus Mus) is 40: 19 autosomes and the X and Y sex chromosomes. Whereas the autosomes and the X Chromosome are telocentric (centromere at one end of the chromosome), the Y chromosome is acrocentric
The most common condition associated with a deletion of the end of chromosome 5 is: cri-du-chat syndrome.
