During interphase, centrosomes are duplicated.
Explanation:
Interphase is one of the two phases of cell cycle (other being mitotic phase).
Interphase is characterized by cell growth and DNA replication. It is subdivided into:
• G1 phase (the first gap phase) - the cell grows and becomes larger and copies organelles

• G2 phase - proteins and organelles are formed.
G2 phase is followed by the beginning of mitotic phase.
