Detailed explanation-1: -A typical cell spends the majority of its time in interphase, which is the phase of the cell cycle. The metabolic or “everyday life” phase of the cell is known as the interphase, during which the cell develops, replicates its DNA in order to be ready for mitosis, and does other “typical” cell operations.

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: -Of the four phases, G1 is most variable in terms of duration, although it is often the longest portion of the cell cycle (Figure 1).

Detailed explanation-4: -The cell cycle consists of a series of steps during which the chromosomes and other cell material double to make two copies. The cell then divides into two daughter cells, each receiving one copy of the doubled material. The cell cycle is complete when each daughter cell is surrounded by its own outer membrane.
