Day 7: Jumpin' Genes!
The Cell Divides
Once the daughter chromosomes have been separated,
the mitotic spindle disassembles, the nuclear
membrane reforms, and the daughter chromosomes begin
to unwind. The centrioles then direct contractile
proteins (like those making up muscle) to assemble
midway between the two new nucleii. These
contractile fibers attach themselves to the cell
membrane. When they contract, they pinch the cell in
two. This stage of mitosis is referred to as
telophase. Mitosis is complete; one cell has become
two.
