Detailed explanation-1: -The interphase is the period when the cell is in a non-dividing state and this can be in different stages: the first gap (G1 ) between the last mitosis and the S phase (phase of DNA synthesis) and the second gap (G2 ) between the completion of the S phase and the next mitosis (M).

Detailed explanation-2: -A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

Detailed explanation-3: -During interphase, G1 involves cell growth and protein synthesis, the S phase involves DNA replication and the replication of the centrosome, and G2 involves further growth and protein synthesis. The mitotic phase follows interphase.

Detailed explanation-4: -G1 (Gap 1) is the phase when the cell grows and functions normally. During this time, a large amount of protein synthesis occurs required for the DNA replication and the volume of the cytoplasm increases.

Detailed explanation-5: -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.
