Detailed explanation-1: -During interphase, the cell grows (G1 ), replicates its DNA (S) and prepares for mitosis (G2 ).
Detailed explanation-2: -Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
Detailed explanation-3: -G1 phase (Gap 1)-Cellular contents excluding the chromosomes, are duplicated. II. S phase (DNA Synthesis)-Each of the 46 chromosomes are duplicated by the cell.
Detailed explanation-4: -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-5: -The first growth phase (G1): During the G1 stage, the cell doubles in size and doubles the number of organelles. The synthesis phase (S): The DNA is replicated during this phase.
