Answer-
Interphase is the preparatory phase of the cell cycle. The cell prepares for mitosis during this phase. It is the longest phase of cell division. It is divided into G11 phase, G22 phase, and S phase.
1) Interphase begins with G11, which stands for ‘Gap 1’. The cells grow and synthesize proteins needed for mitosis.
2) S phase follows G11, This phase involves replicating the cell’s DNA. After the S phase completes, chromosomes have two chromatids, meaning each chromosome has two molecules of DNA.
3) G22 is characterised by the synthesis of more proteins, and organelles like mitochondria grow and divide
