The correct answer is: 2.metaphase.
Mitosis is a process of cell division and it is separatd into phases.
• Interphase-DNA replication (two identical full sets of chromosomes),
• Prophase-chromosomes composed of two sister chromatids with identical genetic information,
• Metaphase- chromosomes line up along the centre of the cell,
• Anaphase- chromatids are pulled apart by the mitotic spindle (one chromatid to one pole and the other chromatid to the opposite pole),
• Telophase- a full set of chromosomes at each pole of the cell.
