Mitosis- Life Cycle of a Cell

Mitosis is a cycle…

with no beginning or end

Mitosis creates…

diploid cells and is for the purpose of tissue repair and growth in animals] DNA coils to form chromosomes during cell division

Interphase-Testing Stage

-Cells carrying on normal activities

-Chromosomes aren’t visible

- Cell metabolism is occurring

-Occurs before mitosis

Stages of mitosis

Prophase, Metaphase, Anaphase, Telophase

Parent cell

Prophase

-DNA + proteins coil into chromosomes, nuclear membrane breaks down, spindle fibers form

-DNA coils tightly & becomes visible as chromosomes

-Nuclear membrane disappears

-Nuceolus disappears

-Centrioles migrate to poles

-Spindle begins to form

Metaphase

-Chromosomes attach to spindle fibers and line up in the center of the cell

-Spindle fibers from centrioles attach to each chromosome

-Cell preparing to separate its chromosomes

- Cell aligns its chromosomes in the middle of the cell

Anaphase

-Identical chromatics separate spindle fibers move them to opposite sides

-Cell chromosomes are separated

-Spindle fibers shorten so chromosomes pulled to ends of cell

Telophase

-Spindle fibers disappear cytogenesis divides the cell in two

-Separation of chromosomes completed

-Cell Plate forms (plants)

-Cleavage furrow forms(animals)

-Nucleus & nucleolus reform

-Chromosomes uncoil

Cytokinesis (Cell plate forming between the two cells)

-Occurs after chromosomes separate

-Forms two, identical daughter cells
