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 …
What are the 4 stages of mitosis and what happens in each?
The process in which the nucleus of a eukaryotic cell divides is called mitosis. During mitosis, the two sister chromatids that make up each chromosome separate from each other and move to opposite poles of the cell. Mitosis occurs in four phases. The phases are called prophase, metaphase, anaphase, and telophase.
What are the events of each stage of mitosis?
Mitosis is divided into five phases:
- Interphase: The DNA in the cell is copied in preparation for cell division, this results in two identical full sets of chromosomes?. …
- Prophase: The chromosomes condense into X-shaped structures that can be easily seen under a microscope. …
- Metaphase: …
- Anaphase: …
What are the stages of mitosis what happens at each stage and why?
The stages of mitosis in detail
|Interphase||The cell spends most of its life in this phase. The DNA in chromosomes copies itself ready for mitosis.|
|Prophase||The DNA in chromosomes and their copies condenses to become more visible. The membrane around the nucleus disappears.|
Where does mitosis occur in the body?
Cell division by mitosis occurs in all human body cells except the gonads (sex cells). During mitosis, the DNA is exactly copied and a new daughter cell created with the same number of chromosomes as the parent cell, ie 46.
What are the two events of 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.
