Detailed explanation-1: -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-2: -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-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. III. G2 phase (Gap 2)-The Cell “double checks” the duplicated chromosomes for error, making any needed repair.

Detailed explanation-4: -The first three phases of the cell cycle, G1, S, and G2 are collectively known as interphase. The following phase of the cell cycle, mitosis, is divided into the five distinct stages of prophase, prometaphase, metaphase, anaphase, and telophase.

Detailed explanation-5: -(A) Interphase is the phase when the cell prepares for the division phase. It includes G1 (gap 1), S (synthesis), and G2 (gap 2) phases.
