10 Questions
During which phase of mitosis do chromosomes align themselves at the equatorial plane of the cell?
Metaphase
What is the main function of the mitotic spindle in mitosis?
Chromosome alignment
Which phase of mitosis sees the centrioles migrating to opposite poles of the cell?
Prophase
What happens to the nuclear envelope during prometaphase in mitosis?
It disassembles completely
Where are the kinetochores located on chromosomes during mitosis?
At the centromere
What happens during anaphase of mitosis?
Microtubules begin to shorten, pulling sister chromatids apart
Which event marks the beginning of telophase in mitosis?
Chromosomes reach the poles of the cell and begin to decondense
In which phase of mitosis do centrosomes move to opposite poles?
Anaphase
Which process involves the separation of the cytoplasm following mitosis?
Cytokinesis
What is a distinguishing feature between mitosis and meiosis in terms of chromosome number?
Mitosis results in diploid daughter cells with the same chromosome number as the parent cell
Study Notes
- Mitosis is a process of cell division that allows for the regeneration of body parts by separating nuclear chromosomes into two identical daughter nuclei.
- The process of mitosis consists of four key phases: prophase, metaphase, anaphase, and telophase, followed by cytokinesis.
- Before entering mitosis, a cell undergoes a period of growth and rest called interphase where genetic material increases.
- During prophase, chromatin condenses to form chromosomes with two sister chromatids, the nucleolus disappears, and the nuclear membrane breaks down.
- In anaphase, sister chromatids separate at the kinetochore and move towards opposite poles, while cytokinesis partitions the cytoplasm either through cleavage furrow in animals or cell plate formation in plants, resulting in two daughter cells.
Learn about the key phases of mitosis - prophase, metaphase, anaphase, and telophase - along with the pre-mitotic interphase and cytokinesis. Understand how genetic material is separated and distributed to form two identical daughter cells.
