S phase: DNA replication occurs in this phase.

G2 phase: cell duplicates all their contents and prepares for mitotic phase.

Mitotic phase:

i) prophase- chromosome condensation occurs,

ii) metaphase - chromosome arranges in meta-plate and spindle binds to each chromosomes  at centromere.

iii) anaphase- chromosome separates from sister chromatids.

iv) telophase- chromosome moves to each ends and formation of nuclear membrane begins.
