Chromosomes: 1 large piece of DNA

Mitosis: Steps of dividing DNA

Chromatin: Loosley coiled DNA, Good for reading instructions

Chromatid: Tightly coiled DNA, Good for transport

Centriole: Connects spindle fibers

Prophase:

• 1st step of mitosis

• Nuclear Membrane disappears

• Nucleolus disappears

• Centrioles begin to move in opposite directions

• Cytoskeleton disappears

• Spindle Fivers grow out of centrioles and centromeres

Metaphase:

• Centrioles at opposite parts

• Sister chromatids are lined up at the equator

• Spindle fibers attach chromosomes to both poles

Anaphase:

• Centromere breaks

• Sister chromatids move toward opposite parts (forms “V”)

Telophase:

• The nuclear membrane and Nucleus reappear

• Spindle Fibers → Cytoskeleton

• Chromatid → Chromatin

Cytokinesis:

• Divide cytoplasm and organelles

• Cytoskeleton chokes the cells in half

• Creates identical daughter cells in interphase
