Phase Characteristics G 1 phase The cell is metabolically most active, cell size increases and organelle duplication takes place in this phase. S phase In this phase, DNA replication, i.e. doubling of DNA content, histone and centriole duplication takes place. G 2 phase In this phase, cytoplasmic growth takes place. Metaphase in M - phase In this stage, chromosomes are highly condensed and the alignment of chromosomes takes place at the metaphasic plate.

Phase	Characteristics
$G_{1}$ phase	The cell is metabolically most active, cell size increases and organelle duplication takes place in this phase.
$S$ phase	In this phase, $DNA$ replication, i.e. doubling of $DNA$ content, histone and centriole duplication takes place.
$G_{2}$ phase	In this phase, cytoplasmic growth takes place.
Metaphase in $M -$ phase	In this stage, chromosomes are highly condensed and the alignment of chromosomes takes place at the metaphasic plate.
