|
Cell cycle |
This is an ordered sequence of events in the eukaryotic cell that is composed of mitosis, interphase growth and DNA synthesis phases. |
- complex series of stages - yeast and amoeba divide to produce two new identical organisms - begins with one fertilized egg cell |
|
|
Mitosis |
This is the process of sorting and distributing the chromosomes. |
- when a cell divides, its nuclear membrane breaks down - individual chromosomes separate and become visible - chromosomes are distributed to the daughter cells |
|
|
Interphase |
This is the period between divisons. |
- individual chromosomes are not visible in the nucleus - DNA replicates during part of ___________ - divided into three parts |
|
|
G1/G0 |
(Gap 1 or pre replication) (Gap 0 or nondividing cells) |
- during ____, cells can stop dividing and enter ___ - _____ stage is a stopping point within ____ - metabolically active - specialized to perform tasks necessary to sustain the life of the organism |
|
|
S |
DNA Synthesis |
- DNA replication in ___ phase results in duplicated chromosomes |
|
|
G2 |
Gap 2 or premitosis |
- cells grow and synthesize RNA - synthesize proteins - synthesize other macromolecules - preform cell's special function in a multicellular organism |
|
|
M |
Mitosis |
- cell division occurs here |
|
|
Restriction point |
This is a point within the cell cycle. Once this point has happened, a cell must go through a full round of the cell cycle. |
- "Point of no return" - when a cell in G0 or G1 receives a signal, it passes through the __________ - cannot return to G0 or G1 stage before going through the cell cycle |
|
|
Cytokinesis |
This is the division of the whole cell. |
- happens after mitosis - movement of the cytoplasm and plasma membrane divides a cell in two |
|
|
Daughter cell |
This is either of the two cells that undergoes cell division by mitosis. |
- genetically identical to the parent cell - they contain the same number and type of chromosomes |
