Cell Cycle
Percentage of the cell cycle is spent in interphase
What is 90%?
The first stage of mitosis.
Prophase
Holds sister chromatids together
What is the centromere?
Mitosis is a form of reproduction for what type of organisms
Unicellular organisms
What structure attaches spindle fibers to the chromosomes?
Centromere
The process in which a cell develops, grows, and divides called
Cell cycle
During which stage do chromosomes line up in the center of the cell?
Metaphase
Identical copies of a chromosome called
What are sister chromatids?
How does mitosis contribute to growth?
By increasing the number of cells in an organism
What is the indentation that forms in animal cells during cytokinesis?
Cleavage furrow
During which phase does a cell perform its normal functions and prepare for division?
Interphase
In which stage are sister chromatids pulled apart?
What are homologous chromosomes?
Chromosome pairs with the same genes in the same locations
What role does mitosis play in repair?
Replacing damaged or dead cells?
What ensures chromosomes are evenly divided between new cells?
Spindle apparatus
Name two things that happen during interphase to prepare for cell division.
What is DNA replication and organelle replication?
What happens in telophase?
Chromosomes uncoil and nuclear membranes reform
Why must DNA be replicated before mitosis begins?
To ensure both new cells have identical genetic information
Why do multicellular organisms undergo mitosis?
For growth, development, and repair?
How many daughter cells are produced at the end of mitosis and cytokinesis?
Two
Why is mitosis important in the cell cycle?
To maintain size, growth, repair, and asexual reproduction?
Immediately follows mitosis
What is cytokinesis?
During which phase does DNA condense into chromosomes?
Prophase
What would happen if mitosis did not occur properly?
Abnormal cell function, disease, or cancer?
Are the daughter cells genetically identical to the parent cell?
Yes
