Study Notes
Chromosome Replication and Condensation
- DNA replicates before cell division.
- Chromosomes condense.
- Each duplicated chromosome has two sister chromatids.
Sister Chromatids and the Centromere
- Sister chromatids are attached to each other.
- The centromere is the narrow part where sister chromatids are joined most tightly.
Chromosome Separation
- Sister chromatids separate during cell division.
- Each separated chromatid becomes a chromosome in a new nucleus.

Description
This quiz delves into the process of chromosome replication and condensation prior to cell division. It covers the structure of sister chromatids, the role of the centromere, and the separation of chromatids during cell division, leading to new nuclei formation.
