Questions and Answers

Match each phase of mitosis with its key event:

Prophase = Chromosomes condense and become visible. Metaphase = Chromosomes align at the cell's equator. Anaphase = Sister chromatids separate and move to opposite poles. Telophase = New nuclei form around separated chromosomes.

Match the following terms with their correct association during cell division:

Mitosis = Cell division for growth and repair. Meiosis = Cell division for sexual reproduction. Interphase = The phase where the cell spends most of its time, growing and duplicating DNA. Cytokinesis = Division of the cytoplasm to form two new cells.

Match the cellular component with its role in mitosis:

Chromosomes = Carry genetic information and are duplicated before mitosis. Spindle Fibers = Responsible for separating chromosomes to opposite ends of the cell. Nucleus = Contains DNA in eukaryotic cells. Cell Membrane = Surrounds the cytoplasm of a cell.

Match the stage of the cell cycle with its main activity:

G1 Phase = Cell grows and performs normal functions. S Phase = DNA replication occurs. G2 Phase = Cell prepares for mitosis, growing and synthesizing proteins. M Phase = Mitosis and cytokinesis occur. Signup and view all the answers

Match the following descriptions with the appropriate term:

Cell Division = The process by which a parent cell divides into two or more daughter cells. DNA Replication = The process of duplicating DNA before cell division. Uncontrolled Cell Division = Characteristic of cancer cells. Identical Cells = The result of mitosis. Signup and view all the answers

Match each process with its significance in maintaining genetic integrity during cell division:

DNA Replication = Ensures each new cell has the correct number of chromosomes. Chromosome Condensation = Allows for efficient movement and separation of chromosomes. Spindle Fiber Attachment = Ensures accurate segregation of chromosomes to daughter cells. Error Checkpoints = Stops cell division if errors are detected. Signup and view all the answers

Match the stage of mitosis with the arrangement of chromosomes:

Prophase = Chromosomes are condensing, but not yet aligned. Metaphase = Chromosomes are aligned at the metaphase plate. Anaphase = Chromosomes are moving towards opposite poles. Telophase = Chromosomes are at opposite poles and decondensing. Signup and view all the answers

Link the cellular structure with its change during mitosis:

Nuclear Membrane = Breaks down during prophase and reforms during telophase. Chromosomes = Condense during prophase and decondense during telophase. Spindle Fibers = Form during prophase and attach to chromosomes during metaphase. Centrosomes = Move to opposite poles of the cell during prophase. Signup and view all the answers

Match the cellular components with their function in anaphase:

Spindle Fibers = Separate sister chromatids. Kinetochores = Attach to spindle fibers and facilitate movement of chromosomes. Motor Proteins = Drive the movement of chromosomes along spindle fibers. Centrosomes = Organize and anchor spindle fibers. Signup and view all the answers

Flashcards

What is Mitosis?

A type of cell division for growth, repair, and cell replacement, not for sperm or egg cells.

Mitosis outcome

Mitosis produces two identical daughter cells, exact copies of the original cell.

Cell's Longest Phase

The majority of a cell's life is spent in interphase where it grows, duplicates DNA, and performs its normal functions.
