What are the stages of mitosis in order from 1-4?
Prophase - chromosomes condense and become visible, mitotic spindle starts to form, nuclear envelope dissolves Metaphase - spindle fibres attach to Choromsomes, chromosomes line up at the equator of the cell Anaphase - chromatids are pulled apart Telophase - New nuclear envelope forms, cell begins to pinch in two
The first phase of mitosis is called?
