What is Mitosis? • Mitosis : Cell division involving somatic (non- sex) cells • Involves only diploid cells – 2n • Form of asexual • Form of asexual reproduction for some life (bacteria & protista fungi) (bacteria & protista, fungi) • End Result : Two genetically identical genetically identical “daughter cells” The Cell Cycle • Defined: Repeating set of events in the life of a cell • Defined : Repeating set of events in the life of a cell • 1) Interphase G1 S G2 – G1, S, G2 • 2) Prophase • 3) Metaphase • 3) Metaphase • 4) Anaphase 5)T l h • 5) Telophase Remember: The cell won’t continue on to the next stage unless the cell is large enough and everything has been copied properly.

What is Mitosis?• Mitosis: Cell division

involving somatic (non-sex) cells

• Involves only diploid cellsy p– 2n

• Form of asexual• Form of asexual reproduction for some life (bacteria & protista fungi)(bacteria & protista, fungi)

• End Result: Two genetically identicalgenetically identical “daughter cells”

Interphasep• Divided into 3 Stages:• G1 Stage• G1 Stage

– Normal function performed

– Cell growth– Organelles replicated

• S Stage• S Stage– Chromatin (DNA

strands) duplicated• G2 Stage

– Cell growthN l f ti– Normal function performed

Prophasep• 1st Mitosis Stage• Chromatin (DNA

strands) coils into chromosomes

• Nucleus dissolvesNucleus dissolves spilling the chromosomeschromosomes

• Spindle fibers fform

Metaphasep• 2nd stage of

mitosismitosis• Spindle fibers

attach toattach to centromeres of each chromosomea o oso

• Spindle fibers pull the chromosomes to the cell’s equator
