Interphase/Mitosis Stages

Cells grows

G1

DNA replication

Synthesis

Cell prepares for division

G2

Phase in between episodes of mitosis

Interphase

Chromatin is loosely coiled and messy

Interphase

Centrosomes duplicate

Interphase

Chromatin condenses and coils up on itself to form chromosomes

Prophase

You an see chromatid (each “leg” or copy of the DNA) being connected by a centromere

Prophase

Centrosomes go to oposite ends of a cell or oposite “poles”

Prophase

Nuclear membrane dissolves

Prophase

Centrosomes form a trail of protein rope called microtubules which form spindle fibres running from one centrosome to the other and provide structure to the cell

Prophase

Longest phase of mitosis

Metaphase

Motor proteins attatch to spindle fibres

Metaphase

Chromosomes line up in the middle of the cell

Metaphase

Motor proteins start pulling so hard on the spindle fibres that the chromosomes split back into their individuals single chromosomes

AnaphaseA

Cells are arranged towards either end of the cells

Anaphase

Each of the new cell structures are reconstructed

TelophaseN

Nuclear membrane reforms

Telophase

Nucleoli reform

TelophaseC

Chromosomes relax back int chromatin

Telophase

Division between two new cells begin with the formation of a clevage

Telophase

Cell membrane pinching inward to divide the cell into two separate daughter cells.

Cytokinesis
