Sister Chromatids |
Two identical copies formed by the replication of a single chromosome. |
One half of the duplicated chromosome. |
|
|
Centromere |
The point on a chromosome by which it is attached to a spindle fiber during cell division. |
A point on a chromosome. |
|
|
Aneuploid |
Having particular genes or chromosomal regions present in extra or fewer copies than in a normal type. |
Not having the same genes as normal. |
|
|
Prophase |
The first stage of cell division during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears. |
Before metaphase. |
|
|
Metaphase |
The second stage of cell division. |
Chromosomes become attached to the spindle fibers. |
|
|
Anaphase |
The stage of mitotic cell division in which chromosomes move away from one another to opposite poles of the spindle. |
Chromosomes move away from each other. |
|
|
Telophase |
The final phase of cell division. |
Where the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed. |
|
|
( Mitotic ) Spindle ( Fibers ) |
Form a protein structure that divides the genetic material in a cell. |
The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells. |
|
|
Spindle Poles |
Is the microtubule organizing center in yeast cells, functionally equivalent to the centrosome. |
It does not contain centrioles. |
|
|
Kinetochore |
A specialized structure on the centromere to which the microtubular spindle fibers attach during mitosis and meiosis. |
Centromere. |
