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 ...

which also causes chromosome disengagement 8. During the next cell cycle, the actual initiation of centriole duplication occurs only when cytoplasmic conditions become permissive during S phase.

Long protein fibers called microtubules extend from the centrioles in all possible directions, forming what is called a spindle. Some of the microtubules attach the poles to the chromosomes by ...

As the centrioles move toward the poles of the cell ... formed between the centrosomes and the newly made microtubules attach to the kinetochore of each chromosome. Encourage students to modify their ...

These centrosomes, composed of centrioles surrounded by a protein ... Rapid spindle formation and chromosome segregation occur in successive cycles, culminating in the release of motile gametes.

Each chromosome is, at this time, actually two identical copies. Each copy is called a chromatid. A spindle begins to form from the centrioles. This spindle is made of fibers. The centrioles begin ...
