5 Questions
What is mitosis and what does it result in?
Mitosis is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. It results in the division of the mother cell into two daughter cells genetically identical to each other.
What are the stages of mitosis?
The stages of mitosis are preprophase (specific to plant cells), prophase, prometaphase, metaphase, anaphase, and telophase.
What happens to the chromosomes during mitosis?
During mitosis, the chromosomes condense and attach to spindle fibers that pull one copy of each chromosome to opposite sides of the cell.
What is the role of cytokinesis in mitosis?
Cytokinesis divides the cytoplasm, organelles, and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components.
What precedes and follows mitosis in the cell cycle?
Mitosis is preceded by the S phase of interphase, during which DNA replication occurs. It is followed by telophase and cytokinesis.
Study Notes
Mitosis Overview
- Mitosis is a type of cell division that results in two daughter cells that are genetically identical to the parent cell.
- Mitosis is essential for growth, development, and tissue repair in multicellular organisms.
Stages of Mitosis
- Interphase: The cell grows, replicates its DNA, and prepares for cell division.
- Prophase: The chromatin condenses into visible chromosomes, and the nuclear envelope breaks down.
- Metaphase: The chromosomes line up at the center of the cell, attached to the spindle fibers.
- Anaphase: The sister chromatids separate and move to opposite poles of the cell.
- Telophase: The nuclear envelope reforms, and the chromatin uncoils to form chromatin.
- Cytokinesis: The cytoplasm divides, and the cell splits into two daughter cells.
Chromosomes during Mitosis
- The replicated chromosomes condense into visible structures during prophase.
- The chromosomes line up at the center of the cell during metaphase.
- The sister chromatids separate during anaphase, ensuring each daughter cell receives a complete set of chromosomes.
Role of Cytokinesis
- Cytokinesis is the physical process of cell division that follows mitosis.
- It divides the cytoplasm and splits the cell into two daughter cells.
Mitosis in the Cell Cycle
- Interphase precedes mitosis, during which the cell grows and replicates its DNA.
- Cytokinesis follows mitosis, dividing the cytoplasm and forming two daughter cells.
- Mitosis is a crucial stage in the cell cycle, ensuring the proper distribution of genetic material to daughter cells.
