Cell Cycle
Interpahse and MItosis
Term | Definition |
---|---|
Interphase | the cell grows and maintains its routine functions as well as its contributions to the internal environment (longest period of time) |
Gap 1 (G1)- Interphase | cell growth occurs and cytoplasmic organelles are replicated (centrioles, mitochondria) |
Synthesis (S)- Interphase | genetic material replicates (DNA) |
Gap 2 (G2)- Interphase | completion of DNA replication |
Prophase | chromosomes condense and become visible; nuclear envelope and nucleolus disperse; spindle apparatus form |
Metaphase | the chromosomes become attached to the spindle fibers, and they align along equator or metaphase plate |
Anaphase | sister chromatids seperate to opposite poles of the cell |
Telophase | nuclear envelopes begin to reassemble around two daughter nuclei; chromosomes and spindle disappears |
Cytokinesis | a cell divides its cytoplasm to produce two daughter cells, and that is accomplished by a structure called the contractile ring; this pinching process is also called the "cleavage furrow," as it is the cleavage of one cell into two cells |
