Cell division
|
Process by which a cell divides into two new daughter cells.
|
Mitosis
|
Part of eukaryotic cell division during which the cell nucleus divides.
|
Ctyokinesis
|
Division of the cytoplasm during cell division.
|
Chromatid
|
One of two identical ''sister'' parts of a duplicated chromosome.
|
Centromere
|
Area where the chromatids of a chromosome are attached.
|
Interphase
|
Period of the cell cycle between cell divisions.
|
Cell Cycle
|
Series of events that cells go through as they grow and divide.
|
Prophase
|
Can take as much as 50 and 60 percent of the total time required to complete mitosis. The first and longest phase of mitosis.
|
Centriole
|
One of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope.
|
Spindle
|
Fanlike microtubule structures that helps separate the chromosomes during mitosis.
|
Metaphase
|
Second phase of mitosis, during which the chromosomes line up across the center of the cell.
|
Anaphase
|
Is the third phase of mitosis. During anaphase, the centromeres that join the sister chromatids split, allowing the sister chromatids to separate and become individual chromosomes.
|
Telophase
|
Fourth and final phase of mitosis. In telophase, the chromosomes, which were distinct and condensed, begin to disperse into a tangle of dense material.
|
Cyclin
|
One of a family of closely related proteins that regulate the cell cycle in eukaryotic cells.
|
Cancer
|
Disorder in which some of the body's own cells lose the ability to control growth.
