Mitosis and Meiosis

G1 phase

• DNA replication

• all enzymes are produced

• all organelles and cytoplasmic components replicate

• cell is dividing

What happens in prophase (mitosis)

• chromosomes condense and become visible

• chromosomes align at the plate

• chromatids are pulled apart by mitotic spindles

• chromatids are segregated

What happens in Metaphase (mitosis)

• chromatids are pulled apart by mitotic spindles

• chromatids are segregated

• chromosomes are aligned at the plate

• chromosomes condense and become visible

What happens in Anaphase (mitosis)

• splitting of the cell

• chromatids are segregated and their DNA decondenses

• chromatids are pulled apart by mitotic spindles

• chromosomes align

What happens in Telophase (mitosis)

• chromatids are segregated and their DNA decondenses

• splitting of cell

• chromosomes condense and become visible

• chromosomes align
