Cell Cycle |
sequence of growth and division of a cell |
|
|
Cell cycle order |
interphase, Mitosis, Cytokinesis |
|
|
Interphase
|
majority of cell's life. growth period of a cell |
|
|
Interphase order |
G1, S phase, G2 phase, |
|
|
G1 phase |
rapid cell growth, protein production is high |
|
|
S Phase |
chromosomes are duplicated, DNA synthesis occurs |
|
|
G2 phase |
centrioles, mitochondria, otherorganelles replicate; protein synthesis is high |
|
|
Mitosis |
period of nuclear divison; 2daughter cells formed |
|
|
Mitosis order |
Prophase, metaphase, anaphase, telophase |
|
|
Prophase |
longest phase.Chromatin coil into visible chromosomes. Nucleusdisappears. Centrioles migrate to opposite ends of cell and spindle fibers begin to form between |
|
|
Metaphase |
centromeres attach to spindlefibers and line up on equator |
|
|
Anaphase |
centromeres split apart and sisterchromatids separate & are pulled apart by the shortening of spindle fibers |
|
|
Telophase |
chromatids reach opp. poles,chromosomes uncoil, nuclear envelope reappears, spindle break down; in plants- cell plate forms; animals- cleavage furrow |
|
|
Cytokinesis |
cytoplasmdivides; cell wall forms or plasma membrane pinches in |
|
|
binary fission |
Genetic material doubles(plasmid), bacteria cell grows and then plate forms dividing into 2 cells. (practically the same thing as mitosis, BUT prokaryotes DO NOT have a nucleus!) |
|
|
Conjugation |
transfer part of chromosome toanother cell via pilus (bridge). Changes up the genetic composition. |
