During cell division the chromosomes are copied and they form sister chromatids. Then the mitotic spindle attaches to the sister chromatids and pulls them apart, splitting the nucleus in two. Then the cell goes through cytokenesis and the cell membrane is pinched together in the center, this divides the organelles and the cytoplasm between the two daughter cells.

What happens to chromosomes during cell division?
The chromsomes split apart and make spindle fibers.
What happens to cell and chromosomes during meiosis?
Cell division takes place in the cells and chromosomes line up along the center of the cell
What happens to chromosomes during anaphase?
what happens to chromosomes during anaphase
What happens during g2 phases?
Chromosomes are checked for errors.In the G2 phase, growth and preparation for cell division occurs.
What happens during telephase in cell division?
A new nuclear envelope forms around each region of chromosomes
What happens to the nucleus during prophase of cell division?
During prophase of cell division, the nucleus condenses and the chromatin (DNA and proteins) inside it becomes tightly coiled into chromosomes. The nuclear membrane also breaks down, allowing the chromosomes to become more visible and ready for division.
What happens to chromosomes during telophase?
By the time the cell is in telophase, the chromosomes have already replicated, condensed, lined up, and migrated to their poles. During telophase the chromosomes are separating as far apart as possible preparing the cell for cytokinesis (division of cytoplasm).
What does meiosis cause the chromosomes to do during cell division?
Meiosis causes the chromosomes to separate and reduce their number in half during cell division.
What is the term for when chromosomes fail to separate during cell division?
The term for when chromosomes fail to separate during cell division is called nondisjunction.
What change occurs in the amount of DNA during meiosis?
During meiosis, the amount of DNA is reduced by half in each cell division. This reduction occurs during meiosis I when homologous chromosomes separate, leading to cells with only one set of chromosomes (haploid). This reduction is necessary to ensure that when egg and sperm cells combine during fertilization, the resulting zygote will have the correct amount of DNA.
Cellular event happen by removing nuclear envelope?
When the nuclear envelope is removed during cell division (mitosis), it allows the chromosomes to align in the center of the cell, ensuring proper segregation of genetic material between daughter cells. This process allows for the formation of the mitotic spindle, which helps separate the chromosomes during cell division.
How is the chromosomes number halved during cell division: through mitosis or meiosis?
The chromosomes number is halved during cell division through meiosis, not mitosis.
