Detailed explanation-1: -Two key events take place, during S-phase in animal cells, DNA replication and duplication of centriole.
Detailed explanation-2: -G2 is the shortest phase of interphase. It is when organelles and proteins necessary for cell division are produced. The cell requires a bunch of proteins and other stuff to separate the chromosomes and divide the cell in half. All of these materials are produced during G2.
Detailed explanation-3: -The G1 phase stands for gap 1 and is when organelles replicate and the cell grows. The S phase stands for synthesis and is when DNA is replicated.
Detailed explanation-4: -The organelles necessary for the cell division (in M phase) are also synthesized in the S phase. The microtubules that will be used to mobilize the chromosomes in M phase are assembled at G2.
Detailed explanation-5: -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.
