During mitosis, chromosomes must be accurately segregated to opposite sides of the cell by a microtubule (MT)-based structure known as the mitotic spindle. Additionally, an MT-independent structure, the so-called “spindle matrix,” has been proposed to assist mitosis.
What 3 things happen during mitosis?
In mitosis, the nuclear DNA of the cell condenses into visible chromosomes and is pulled apart by the mitotic spindle, a specialized structure made out of microtubules. Mitosis takes place in four stages: prophase (sometimes divided into early prophase and prometaphase), metaphase, anaphase, and telophase.
What 2 things happen during mitosis?
Mitosis is a process where a single cell divides into two identical daughter cells (cell division).
- During mitosis one cell? divides once to form two identical cells.
- The major purpose of mitosis is for growth and to replace worn out cells.
What activities do occur during mitosis?
These basic events of mitosis include chromosome condensation, formation of the mitotic spindle, and attachment of chromosomes to the spindle microtubules. Sister chromatids then separate from each other and move to opposite poles of the spindle, followed by the formation of daughter nuclei.
What type of cells undergo mitosis?
Both haploid and diploid cells can undergo mitosis. When a haploid cell undergoes mitosis, it produces two genetically identical haploid daughter cells; when a diploid cell undergoes mitosis, it produces two genetically identical diploid daughter cells.
What happens during each stage of mitosis?
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope …
Where does mitosis occur in the body?
Mitosis is an active process that occurs in the bone marrow and skin cells to replace cells that have reached the end of their lives. Mitosis occurs in eukaryotic cells. Although the term mitosis is frequently used to describe the entire process, cell division is not mitosis.
How does mitosis cause two daughter cells?
Mitosis leads to two daughter cells when the DNA is duplicated and the cell splits. THe cells goes through interphase, prophase, metaphase, anaphase, and telophase. … When the chromosomes line up in the center they have reached metaphase. The chromosomes then split apart during telophase.
