Cell Division :Mitosis Flashcards
(26 cards)
What is mitosis?
Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.
True or False: Mitosis occurs only in somatic cells.
True
What are the main phases of mitosis?
The main phases of mitosis are prophase, metaphase, anaphase, and telophase.
Fill in the blank: During ____ phase, chromosomes condense and the nuclear envelope breaks down.
prophase
During which phase do chromosomes line up at the cell’s equatorial plane?
Metaphase
What happens during anaphase?
During anaphase, sister chromatids are pulled apart to opposite poles of the cell.
True or False: Cytokinesis is part of mitosis.
False
What is the role of the spindle fibers during mitosis?
Spindle fibers help to separate chromosomes during cell division.
Fill in the blank: The phase where the nuclear envelope re-forms is called ____ phase.
telophase
What is the significance of mitosis in multicellular organisms?
Mitosis is significant for growth, tissue repair, and asexual reproduction.
What is the result of mitosis in terms of chromosome number?
The result of mitosis is that the daughter cells have the same number of chromosomes as the parent cell.
During which phase does DNA replication occur before mitosis begins?
Interphase
True or False: Mitosis ensures genetic variation in daughter cells.
False
What is the term for the point where two sister chromatids are joined?
Centromere
What structure forms during prophase to assist in chromosome movement?
The mitotic spindle
During which phase do the chromosomes become visible under a microscope?
Prophase
What is the purpose of checkpoints during the cell cycle?
Checkpoints ensure that the cell is ready to proceed to the next phase of the cycle.
Fill in the blank: The phase following mitosis that divides the cytoplasm is called ____.
cytokinesis
What is the difference between mitosis and meiosis?
Mitosis produces two identical daughter cells, while meiosis produces four genetically diverse gametes.
True or False: Mitosis is a form of asexual reproduction.
True
What is the role of cyclins in the cell cycle?
Cyclins regulate the timing of the cell cycle by activating cyclin-dependent kinases.
What happens to the nuclear envelope during prophase?
The nuclear envelope breaks down during prophase.
What occurs during cytokinesis in animal cells?
In animal cells, cytokinesis occurs through a cleavage furrow that pinches the cell into two.
Fill in the blank: The genetic material is duplicated during ____ phase of interphase.
S phase
