The Cell Cycle
The cell cycle
• The life of a cell
• The alteration between dividing and not dividing
The cell cycle
Interphase
• The nondividing part of the cell cycle
• The nuclear membrane is intact throughout interphase
• Split into 3 phases
• G1 phase, S phase, and G2 phase
G1 Phase
• Typically the longest phase of the
entire cell cycle
• The cell grows and produces cell
components
• The DNA is loosely spread out,
and you can’t see individual
chromosomes (chromatin form)
S Phase
• DNA is replicated
• Every DNA molecule is
copied exactly, forming 2 sister
chromatids that stay attached
to each other
G2 Phase
• Cell prepares for division
• Makes the cytoskeleton
proteins it needs to move the
chromosomes around
Mitosis
• Division of genetic material and nucleus
of the cell leading up to cell division
Prophase
• DNA appears as
chromatin coils that
pair up as they
condense.
• Nuclear membrane
disappears
Metaphase
• Chromatid pairs line up
along the middle of the
cell
• Centrioles form spindle
fibers attaching the
chromatid pairs at their
centromeres
Anaphase
• Chromatid pairs separate
and are pulled towards the
cells poles by the spindle
fibers
Telophase
• Cells get ready to divide
into two by forming new
nuclear membranes
around the separated sets
of chromosomes
Cytokinesis
• After mitosis ends
• Cytoplasm and
organelles of the cell
divide forming two
identical cells
