Definitions:

Centromeres

The region of a chromosome where the two sister chromatids are joined, playing a crucial role in the movement of chromosomes during cell division.

Sister Chromatids

Identical copies formed by the replication of a chromosome, with both copies joined together by a common centromere.

Chromosomes Decondense

A process where chromosomes relax from their highly structured and compact form to a less condensed, more accessible state, typically occurring at the end of mitosis or meiosis.

Telophase

The final phase of cell division, during which the chromosomes de-condense, nuclear envelopes re-form around the divided chromosomes, completing cytokinesis.
