Answer:

Mitotic phase

Explanation:

Cell cycle is composed of interphase and mitotic phase. Interphase is aphase of cell preparation. It is subdivided into:

  • G1 (gap 1 phase)-the cell grows and becomes larger
  • S phase- replication of DNA, duplication of centrosomes
  • G2 (gap 2 phase)-proteins and oranelles are made

Mitotic phase is phase of cell division, chromosomes are separated, daughter cell get identical sets of chromosomes. It is followed by cytokinesis-separation of cytoplasm. Stages of mitosis are:

  • prophase-condensation of chromatin into chromosomes,  the nuclear envelope breaks down, mitotic spindle formation
  • metaphase-the chromosmes line up (metaphase plate)
  • anaphase-the siste chromatides move toward opposite cell poles
  • telophase-the nuclear envelope forms again, cell division is almost complete
