Found in eukaryotes in the chromosomal material in a cells nucleus. |
In the nucleus |
|
|
Mutation |
A change in the gene, chromosome or unit. |
Changingmu |
|
|
Mutagen |
Causes the changes in mutation. |
Makes the change happen |
|
|
Excision repair |
Fixing damaged DNA, and replacing it with a new one. |
damaged DNA |
|
|
Sister chromatids |
Identical chromosome brought together by centromere. |
Separate during nuclear division. |
|
|
Centromere |
Holds sister chromatids together. |
Attaches to spindle in mitosis |
|
|
Aneuploid |
A certain number of chromosomes that isn't identical to the haploid for that species. |
Doesn't match up |
|
|
Prophase |
Occurs in the mitosis, a certain stage where chromosome strands that are replicated condense. |
Spindle forms in this stage |
|
|
Metaphase |
A stage that occurs in mitosis and meiosis where chromosomes are moved to the center of the spindle. |
Chromosomes are attached to microtubules |
|
|
Anaphase |
Stage that occurs in cell division where chromosomes separate towards different ends of the cell. |
Opposite ends of the cell |
|
|
Telophase |
Final stage in mitosis, and meiosis I and II. Characterized by two nuclei forming at each end of the cell. |
Final stage, opposite ends |
|
|
(Mitotic) Spindle (Fibers) |
Made of proteins, and microtubules. Divides chromatids |
During nuclear division |
|
|
Spindle poles |
One of two cellular regions. Each at the tip of mitosis spindle. |
The daughter nuclei form here during mitosis |
|
|
Kinetochore |
A disklike structure located on centromere. |
Connects chromosomes to mitosis spindle |
|
|
Cyclins |
A pack of proteins, they regulate progression of a cell going through the he cell cycle. |
Concentrations rise and fall |
|
|
Kinases |
Catalyzes substrates made my ATP. |
Works with ATP |
|
|
Cell- cycle arrest |
A major stop in cell cycle that occurs when DNA has been damaged. |
A halt or stop |
|
|
Cancer |
A pack of disease that grows uncontrollably |
