Mitosis
Part C
Question | Answer |
---|---|
What are the two main phases of interphase? | The two main phases of interphase are the growth phase (G1) and the synthesis phase (S). |
What is mitosis? | Mitosis is the process of cell division that results in two genetically identical daughter cells. |
What is the first stage of mitosis called? | The first stage of mitosis is called prophase, during which the chromatin condenses into chromosomes. |
In which stage of mitosis do the chromosomes align in the center of the cell? | The chromosomes align in the center of the cell during metaphase. |
What happens during anaphase? | During anaphase, the sister chromatids are pulled apart and move towards opposite poles of the cell. |
What is the final stage of mitosis? | he final stage of mitosis is telophase, during which the chromosomes begin to decondense and a nuclear envelope reforms around each set of chromosomes. |
What are cell checkpoints? | Cell checkpoints are control mechanisms in the cell cycle that ensure the cell is ready to proceed to the next phase. |
What is cytokinesis? | Cytokinesis is the process of dividing the cytoplasm of a cell to form two separate daughter cells. |
What is apoptosis? | Apoptosis is programmed cell death, which is a normal part of the development and maintenance of multicellular organisms. |
What are cancer cells? | Cancer cells are cells that have lost the ability to control their growth and division, leading to the formation of tumors. |
What is a tumor? | A tumor is a mass of abnormal cells that can be either benign (non-cancerous) or malignant (cancerous). |
What role do cell checkpoints play in the cell cycle? | Cell checkpoints ensure that the cell is ready to progress to the next phase of the cell cycle, preventing the division of damaged or incompletely replicated cells. |
How do cancer cells differ from normal cells in terms of growth and division? | Cancer cells grow and divide uncontrollably, unlike normal cells which follow a regulated cell cycle. |
