Mitosis

Stages of mitosis

Prophase, metaphase, anaphase, telophase

Stage one of prophase

Chromatin fibres made of proteins, rna and dna begin to coil and condense to form chromosomes, nucleolus disappears and nuclear membrane begins to break down

Stage 2 of prophase

Protein micro tubules form spindle shared structures that link to the cell poles, fibres forming spindle are necessary to move chromosomes into correct position before division

Stage 3 of mitosis

2 centrioles migrate to opposite poles of the cell, centrioles are cylindrical bundles of proteins and help in the formation of the spindle

Stage 4 of mitosis

Spindle fibres attach to specific areas on centromeres and start to move the chromosomes to the center of the cell

Stage 5 of mitosis

By the end of prophase the nuclear envelope has disappeared- how you can tell between early and late prophase
