anaphase
Sister Chromatids separate during anaphase.
metaphase
During S phase of inter phase .
Metaphase,
Anaphase
There are two chromatids for each chromosome before the S-phase. The S-phase is wherein DNA of each chromosome is replicated.
S phase
The sister chromatids first appear in the S phase of the cell cycle.
Sister chromatids are present in G1 phase of the cell cycle following DNA replication in S phase. Sister chromatids are two identical copies of a chromosome joined together at the centromere. During G1 phase, the cell prepares for DNA replication in the subsequent S phase.
prophase
During the S-phase of the cell cycle, chromatids are duplicated. Precise duplication of the chromatids is important in order to prevent genetic abnormalities.
