Name The Phase
Mitotic spindle starts to form, chromosomes start to condense, nucleolus is gone.
Early Prophase
The longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis.
Interphase
True or False; cytokinesis is the final step in cell division after mitosis
True
Uncontrolled cell growth
Nuclear envelope breaks down, chromosomes fully condensed
Synthesis phase; the cell synthesizes a complete copy of the DNA in its nucleus
S phase
True or False: Cytokinesis consists of three major steps
False: There are four major steps in cytokinesis.
True or False: In order for cancer cells to be present, apoptosis needs to occur
False; Apoptosis is programmed cell death.
Microtubules push poles apart. Kinetochore microtubules pull chromosomes towards poles
Anaphase
Cell division; also known as the M phase. This is where the cell divides it previously-copied DNA and cytoplasm to make two new, identical daughter cells.
Mitosis (M phase)
What powers the myosin motor
ATP
What cells avoid during cell division?
Checkpoints
Chromosomes line up at a specific plate that also shares the name of this phase.
Metaphase
First gap phase; the cell grows larger and organelles are copied
G1 phase
Actin and microtubules are part of what?
Cytoskeleton
Promotes cell growth in the cell which when activated results in cancer
Positive regulators
Chromosomes start to decondense, spindle disappears, nuclear membrane reforms, nucleolus reappeares
Telophase
Second gap phase; the cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis
What is the purpose of the molecular motor, myosin, in cytokinesis?
Suppresses the formation of tumors which become inactive during cancer
Negative regulators
