Cell Cycle
|
A series of 3 main stages of cellular reproduction: interphase, mitosis, cytokinesis
|
|
|
DNA
|
A molecule that carries genetic information in all living systems and is in the shape of a double helix.
|
|
|
Chromatin
|
Relaxed form of DNA in the nucleus of a cell.
|
|
|
Chromosome
|
Condensed form of DNA that carries genetic information from one generation to another
|
|
|
Interphase
|
First stage of the cell cycle during which a cell grows and
MAKES AN EXACT COPY OF ITS DNA |
|
|
Sister Chromatid
|
Structure that contains identical DNA copies and is formed during DNA replication during interphase stage
|
|
|
Centromere
|
Cell structure that joins two sister chromatids
|
|
|
Mitosis
|
Second main stage of the cell cycle during which the two copies of DA divides and two identical daughter cells are produced
|
|
|
Prophase
|
First stage of mitosis during which the cell's chromatin condenses into chromosomes
|
|
|
Cytokinesis
|
The part of the cell cycle during which the cell's cytoplasm divides, creating a new cell
|
|
|
Telophase
|
Last stage of mitosis in which nucleoli reappear and the cell is preparing to divide
|
|
|
Anaphase
|
Stage of mitosis in which sister chromatids are pulled apart and the chromosomes are moved to the opposite poles of the cell
|
|
|
Spindle Apparatus
|
Structure made of spindle fibers, centrioles and aster fibers; involved in moving and organizing chromosomes before the cell divides
|
|
|
Metaphase
|
Stage of mitosis in which the sister chromatids are moved to the middle (equator) of the cell
|
