mitotic phase+ mitosis

mitotic cell division

2 daughter cells genetically identical to the original cell

-1 cell → 2 identical cells

2 events of mitotic cell division

1. mitosis

2. cytokinesis

mitosis

nuclear division

-mito=NUCLEUS

cytokinesis

Cytoplasmic division

-cyto= CYTOPLASM

4 phases of mitosis - “PMAT”

1.prophase

2.metaphase

3.anaphase

4. telophase

prophase

Chromatin supercoils into chromosomes; sister chromatids are joined at centromeres; spindle fibers begin growing; nuclear envelope disintegrates

-P = PREPARE

chromatin

material that supercoils into chromosomes

-Chromatin → chromosomes

sister chromatids

Duplicate, identical chromatids joined at the centromere

-Sisters = identical twins

centromere

Region joining sister chromatids

-Center = joins

spindle fibers

Elongated microtubules that help move chromosomes

-Spindle = pulls chromosomes

metaphase

Chromosomes line up on the equatorial plate

-M=middle

Equatorial plate

Middle of the dividing cell where chromosomes line up

-Equator = middle

Mitotic spindle

Structure formed by spindle fibers during mitosis

-Spindle = chromosome movement

Anaphase

Sister chromatids are pulled apart toward opposite poles, cytokinesis start

-A = APART

Opposite poles

Opposite ends of dividing cell

Telophase

Nuclear envelopes form around each set of chromosomes, creating two nuclei

-T= TWO NUCLEI

Cleavage furrow

Appears as cytokinesis continues in telophase
