Respuesta :
They need to replicate the full amount of their DNA so that there are two complete copies for each daughter cell to get one.
The "cell cycle" consists of a resting phase or G0 phase followed by Interphase, which is divided into G1, S and G2 phases. The G1 phase prepares the cell to replicate its DNA, the replication of the DNA then takes place in the S phase, and then during the G2 phase the cell prepares to enter the M phase which is when the actual mitosis or cell division happens.

Cells need to do between divisions to make sure that a full set of DNA gets passed on to each daughter cell - The DNA must be copied so there is a full set of DNA to pass on to each daughter cell.
Cells need to grow between divisions to make sure that they don't just get smaller and smaller.
- A lot of the growth that a cell does between divisions occurs during the second growth phase of the cell cycle.
- The second growth phase takes place after DNA is replicated that is essential before the cell divides.
- The replication of DNA ensures that a full set of DNA gets passed on to each daughter cell.
Thus, The DNA must be copied so there is a full set of DNA to pass on to each daughter cell.
