The cell makes a copy of its DNA

Detailed explanation-1: -Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents.
Detailed explanation-2: -Stages of the cell cycle The G1 stage stands for “GAP 1". The S stage stands for “Synthesis". This is the stage when DNA replication occurs. The G2 stage stands for “GAP 2". The M stage stands for “mitosis", and is when nuclear (chromosomes separate) and cytoplasmic (cytokinesis) division occur.
Detailed explanation-3: -Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA. So, S stands for DNA synthesis.
Detailed explanation-4: -During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2).
Detailed explanation-5: -About the Cell Cycle The Cell Cycle consists of 3 stages: Stage 1-The cell grows, the DNA is made into two copies and more organelles are made. Stage 2-Mitosis in which the nucleus divides inside the cell. Stage 3-The cell splits into two identical daughter cells.
