Timeline in Pictures
Real mitotic cells can be visualized through the microscope by staining them with fluorescent antibodies and dyes. These light micrographs are included below.
-
Early prophase: Nonkinetochore microtubules, shown as green strands, have established a matrix around the degrading nucleus, in blue. The green nodules are the centrosomes.
-
Early prometaphase: The nuclear membrane has just degraded, allowing the microtubules to quickly interact with the kinetochores on the chromosomes, which have just condensed.
-
Late metaphase: The centrosomes have moved to the poles of the cell and have established the mitotic spindle. The chromosomes, in light blue, have all assembled at the metaphase plate, except for one.
-
Anaphase: Lengthening nonkinetochore microtubules push the two sets of chromosomes further apart.

“Women who marry early are often overly enamored of the kind of man who looks great in wedding pictures and passes the maid of honor his telephone number.”
