Prometaphase
The centrioles are now at opposite ends of the
cell.
The spindle fibers from both of the centrioles
attach to each one of the chromosomes.

Prometaphase I
Same as in mitosis, except that the spindle fibers
from each centriole attach to one chromosome of a
matching chromosome pair.
In other words, the fibers from one centriole attach
to 23 chromosomes, and the fibers from the other
centriole attach to the other 23 chromosomes.
(Again, only four chromosomes are shown here in
order to simplify the illustration.)
