Interphase is the longest phase in the cell cycle and contain three sub phases and one checkpoint at the end of every checkpoint.
G₁ phase: In this phase the size of the cell increases and nearly becomes double, the raw material for DNA synthesis is synthesised e.g: mRNA and proteins(histone).
S phase: In synthesis phase replication of DNA takes place and amount of DNA become double so that it can be evenly distributed between daughter cells.
G₂ phase: In this phase cell continues to grow and synthesize proteins. cell prepare itself to move in mitotic phase so it can divide.
