Cell Growth and Division (chapter 10)
The third phase of mitosis, during which the chromosome pairs separate and
move toward opposite poles.
Cancer Disorder in which some of the body's own cells lose the ability to control growth.
Cell Cycle Series of events that cells go through as they grow and divide.
Cell Division Process by which a cell divides into two new daughter cells.
One of two tiny structures located in the cytoplasm of animal cells near the
nuclear envelope. Anchors spindle fibers during cell division.
Centromere Area where the chromatids of a chromosome are attached.
Chromatid One-of-two identical "sister" parts of a duplicated chromosome.
One of a family of closely related proteins that regulate the cell cycle in
Phase of the cell cycle where the cell spends most of it's time growing and
performing it's specified job.
G2 Phase Shortest of all the phases in interphase.
Longest phase of the cell cycle (G1, S, G2). Period of the cell cycle between cell
Mitosis Part of eukaryotic cell division during which the cell nucleus divides.
M-Phase The 4th phase of the cell cycle, where mitosis and cytokinesis occur.
First and longest phase of mitosis (50% - 60% of total time), during which the
Prophase chromosomes condense and become visible and the centrioles separate and take
up positions on opposite sides of the nucleus.
Sister Chromatids Two identical copies of a chromosome that are attached at the centromere.
The 2nd stage of the cell cycle, where chromosomes (DNA and proteins) are
Fan-like microtubule structure that helps separate the chromosomes during
Stem Cells An unspecialized cell that gives rise to differentiated cells.
The comparrison of the growth rate of surface area and the volume of cells
Fourth and final stage of mitosis, during which the chromosomes begin to
disperse into a tangible of dense material (chromatin).
