Cell Division
Cell Cycle
Interphase
S Phase
DNA Replication
G2 Phase
Growth
Prepares for mitosis
Checkpoint (cyclin and CDK)
G1 Phase
Growth
G0 Checkpoint (cyclin and CDK)
M Phase (Mitosis)
Prophase
Centrioles form as well as spindle fibers appear
Chromatin condense into chromosomes
Nuclear encelope Dissovles
Anaphase
Sister chrmatins seperate and move to the opposite side of the cell
spidle fibers shorten
Metaphase
Spindle fibers connect to the chromosomes at centromere
Chromosomes line up in the middle
Telophase
Centrioles depolarize and spindle fibers dissapear
Chromosomes decondense into chromatin
Nuclear encelope reappear
cytokinesis
Division of Ctoplasm
Asexual Reproduction
Diploid (2n)
Does not increase variation
Produces identicle copies
Cancer
Tumors
Malignant
Benign
Regulation of cancer
Anchorage depedence
Keeps the cell held together
density-dependent inhibition
can grow on top of one another
Checkpoint
Cyclin and CDK
Uncontrolled cell division
Stem Cells
Unsprecialized/Undiffrentiated
Animal Cells
adult stem cell
Umbillical cord cells
Embyronic Cells
Plant Cells
meristem
Somatic Cells
Noromal Body Cells
Specialized/Diffrentiated
Variation is diffrence between organisms
