Telophase
Chromosomes become visible during _____.
Prophase
During prophase, the chromatin fibers become discrete chromosomes.
Centromeres divide and sister chromatids become full-fledged chromosomes
during _____.
Anaphase
During anaphase, sister chromatids separate and daughter chromosomes
migrate to opposite poles.
Spindle fibers attach to kinetochores during _____.
Prometaphase
Attachment of spindle fibers to kinetochores is one of the events of
