The answer is telophase.
Metaphase is when chromosomes attatch to spindle fibers in the phase of mitosis.
Chromosomes attach to the mitotic spindle during the metaphase of mitosis. Part of the answer depends on how you define the stages of mitosis and not everybody does this the same way. The short answer is all of them.
The answer is PROPHASE. there are four phases in Mitosis: prophase, anaphase, metaphase, and telophase.
Metaphase is the stage when spindle fibers attach to chromosomes. Metaphase is the second stage of cell division, between prophase and anaphase.
Prophase
telophase
anaphase
Chromosomes align on the spindle equator during the metaphase. During the metaphase the chromosomes meet on an imaginary line between the two poles.
During early anaphase of mitosis the centromeres of chromosomes split to allow the sister chromosomes to move to the opposite side of the spindle.
metaphase
in metaphase.
Spindle fibers are thin tubes that form between the centrioles during mitosis. True..
