|
Cell Division
|
The process by which a cell divides into two new daughter cells
|
|
|
Mitosis
|
The first stage of cell division where the cell nucleus is divided
|
|
|
Cytokinesis
|
The second stage of cell division where the cytoplasm of a cell is divided.
|
|
|
Chromatid
|
One of two identical "sister" parts of a duplicated chromosome
|
|
|
Centromere
|
The area where the chromatids of a chromosome are attached
|
|
|
Cell Cycle
|
The series of events that cells go through as they grow and divide
|
|
|
Interphase
|
The period of the cell cycle between cell divisions. The DNA is still in the form of chromatin and there is a visible nucleus. This is the longest phase.
|
|
|
Prophase
|
The first and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus. Nucleolus disappears and the nuclear envelope breaks down.
|
|
|
Metaphase
|
The second phase of mitosis, during which the chromosomes line up across the center of the cell.
|
|
|
Anaphase
|
The third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles. There is equal division between all the organelles in the cell.
|
|
|
Telophase
|
The last stage of mitosis, during which the chromosomes begin to disperse into a tangle of dense material. The cell plate begins to appear and in animal cells the pinch between the cell is called a furrow.
|
|
|
Spindle
|
A fanlike microtubule structure that helps separate the chromosomes.
|
|
|
Cyclin
|
One of a family of closely related proteins that regulate the cell cycle in eukaryotic cells.
|
|
|
Cancer
|
A disorder in which some of the body's own cells lose the ability to control growth
|
|
|
Centrioles
|
Two tiny structures located in the cytoplasm near the nuclear envelope that separate and take up positions on opposite sides of the nucleus.
