The DNA and chromosomes divide with it
the four parts of mitosis are prophase,metaphase, anaphase, and telophasein prophase, the nuclear envelope breaks down and a spindle forms between to centrioles. in metaphase,the chromosomes align along the equator of the cell.in anaphase, the chromatids (duplicated chromosomes) are seperated.in telophase,the two cells begin to pull apart, but with plant cells, a cell wall is built in between the two cells.
In nondividing cells, the condensed parts of chromosomes that are visible are the chromatin material, consisting of DNA and proteins. The chromatin is organized into distinct structures called chromatin bodies or chromocenters. These structures are regions where specific genes or DNA sequences are actively or passively transcribed.
When abnormal cells divide and create other abnormal cells, it can lead to the formation of a tumor or mass of cells. This can result in the growth of cancer or other diseases if left unchecked. Additionally, these abnormal cells may also spread to other parts of the body through a process called metastasis.
In fact diploid cells are divided by meiosis. The process of meiosis is to divide a diploid cell into four haploid cells to produce gametes. In the second stage of meiosis it divides the two cell into to equal parts without duplicating the new genetic material. If you did this with a haploid cell, you would end up with a 1/4 of the original number of chromosomes. For example if a human haploid chromosome divided it would only have 11.5 chromosomes.
There are many differences between meiosis and mitosis, and it can all be summed up by understanding they have different functions in life processes. Mitosis is all about creating cells that are identical to each other asexually. This provides multi-cellularity in multicellular beings. Meiosis, on the other hand, is all about the production of gametes (sex cells) from a single germ cell in order to make sexual reproduction possible. Taking all of this into considering, Mitosis is seen as being a part of a cyclical cell life cycle, so it happens more than once. Meiosis is a process that happens only once for a germ cell largely because it is a process that creates haploid cells from diploid cells. Note that because of these differences Mitosis requires the replication of DNA to occur in order for diploid cells to create more diploid cells. Diploid meaning that a full set of chromosomes are present; human diploid cells would have 46 chromosomes, 23 from the mother and 23 from the father that are paired up with each other. Haploid, would mean 23 human chromosomes in total; with regards to Meiosis, the chromosomes would be a combination of the genes that an individual inherited from his or her parents. In Meiosis, which is divided into two parts, replication of DNA occurs before Meiosis I is carried out, but no replication occurs before proceeding to Meiosis II in order to achieve creating haploid cells.
No. Chromosomes are parts of cells, and sex cells are just one of many types of cells.

they duplicate
The same as in every other cell of their bodies. All chromosomes are present in all cells, just different parts are activated so they influence the cells.
The characteristic number of chromosomes in human somatic cells is 46, which is comprised of 23 pairs of chromosomes. These pairs include one chromosome from each parent, with 22 pairs of autosomes and one pair of sex chromosomes (XX for females and XY for males).
Yes, as a matter of fact, all living that reproduce via mitosis or meiosis will form chromosomes. Chromosomes are only formed during these ways of reproducing. At all other parts of a cell's life, chromosomes are stringy matter called chromatin.
The cells begin to divide into two main parts.
it occurs in the gametes, the sex cells. where mitosis occurs in all other cells that have two halves of chromosomes, meiosis occurs in cells which only have one half of the chromosomes.
During metaphase, chromosomes line up in the middle of the cell to ensure that they are evenly distributed to the two daughter cells during cell division. This alignment helps to ensure each daughter cell receives a complete set of chromosomes. It also allows for proper segregation of genetic material.
Sister chromatids are identical while homologous chromosomes are merely similar.They are different because they separate the cells and then they become babies but only the homologous chromosomes do.
