Transcript
Phases of Mitosis and Cell Cycle
Centrioles
Interphase
* Cell spends most of its life in
this phase
* Cell grows
* Cell replicates its DNA
Prophase
* Chromatin in nucleus condenses to
form chromosomes
* Centrioles produce spindle fibers
* Nuclear Envelope breaks down
Metaphase
* Spindle fibers attach to each
chromosome at the centromere
* Chromosomes line up in the
middle of the cell
Anaphase
* Spindle fibers pull chromosomes
apart causing cell membrane to
elongate
* Sister chromatids move to
opposite ends of cell
Telophase
* Two new nuclear envelopes form
around the group of sister
chromatids
* Spindle fibers disappear
Cytokinesis
* Cytoplasm pinches in half form
two identical daughter cells with
equal number of chromosomes
