|
Cell Cycle |
The series of events that take place in the eukaryotic cell that lead up to its division and create two daughter cells. |
|
|
Mitosis |
A type of cell division that results in two identical daughter cells. |
|
|
Interphase |
The resting phase between successive mitotic divisions of a cell. |
|
|
G1/G0 |
The stages in which the cell is just doing its daily job, not dividing. |
|
|
S |
The stage prior to mitosis where the cell chromosomes are replicated. |
|
|
G2 |
The second growth period of the cell prior to mitosis where the cell forms the materials that make the spindle. |
|
|
M |
The process on cell division where the nucleus splits, consisting of four stages. This is mitosis. |
|
|
Restriction Point |
Once the cell starts the process of cell division after G1 it can't turn back, that's the restriction point. |
|
|
Cytokinesis |
The cytoplasmic division of the cell at the end of mitosis. |
|
|
Daughter Cell |
One of two of the resulting cells at the end of mitosis. |
|
|
Nucleotide Base Pairing |
Any of the hydrogen bonded purine and pyrimidine bases that form the links between the sugar-phosphate and nucleic acid molecules. |
|
|
Hydrogen Bond |
A weak bond between molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other. |
|
|
Antiparallel |
Parallel but moving or oriented in opposite directions. |
|
|
Centromere |
The point on a chromosome by which it is attached to a spindle fiber during cell division. |
|
|
Aneuploid |
A cell with extra or fewer chromosomes than normal. |
|
|
Prophase |
The first stage of the cell cycle where the chromosomes become visible and the nuclear envelope disappears. |
|
|
Metaphase |
The second stage of cell division during which the chromosomes become attached to the spindle fibers. |
|
|
DNA Polymerase |
A type of enzyme responsible for forming new copies of DNA in the form of nucleic acid molecules. |
|
|
Semiconservative Replication |
Produces two copies that each contain one of the original strands and one new strand. |
|
|
Histone |
Any of a group of basic proteins found in chromatin. |
|
|
Chromosome |
A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carries genes. |
|
|
Chromatin |
The material of which the chromosomes of organisms other than bacteria are composed. |
|
|
Mutation |
A change in the structure of he nucleotide bases in the DNA strand. |
|
|
Mutagen |
An agent, such as radiation or a chemical substance , that causes genetic mutation. |
|
|
Excision Repair |
When a region of the DNA strand is removed and replaced by the DNA polymerase. |
|
|
Sister Chromatids |
Pieces of identical DNA that are crucial in the process of cell replication and division. |
