mitosis and the cell cycle

Eukaryotic cell cycle

Prophase

Prophase

Chromosomes condense and compact into chromatids

Nuclear envelope disintegrates - chromosomes are liberated

Centrosomes separate to opposite sides of the nucleus​

Prometaphase

Prometaphase

Chromosomes congres to the centre of the cell

Micro tubules nucleated by the centrosomesform a bipolar spindle

Chromosomes are captures by micro tubules ​

Metaphase

Metaphase

Chromosomes are aligned at the cell centre and remain condensed and cohesed

Micro tubules maintain a symmetrical bipolar spindle ​

Anaphase

Anaphase

Cohesion is lost from sister chromatids

Chromosomes more to opposite spindle poles

Centromères remain the same distance apart ​

Telophase

Telophase

Chromosomes at opposite end of the cell start to decondense

Nuclear envelope starts to reform

Cleavage furrow formed ​

Cytoskeleton

Cytokinesis

Chromosomes condense and are packaged into nuclei

Cytoplasm splits forming 2 identical daughter cells ​
