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: -During interphase, the cell undergoes normal growth processes while also preparing for cell division. It is the longest phase of the cell cycle, cell spends approximately 90% of its time in this phase. In order for a cell to move from interphase into the mitotic phase, many internal and external conditions must be met.

Detailed explanation-3: -However, mitosis and cytokinesis last only about an hour, so approximately 95% of the cell cycle is spent in interphase-the period between mitoses. During interphase, the chromosomes are decondensed and distributed throughout the nucleus, so the nucleus appears morphologically uniform.

Detailed explanation-4: -The G1 phase is the longest in the cell cycle. It’s the beginning of the interphase. The cell prepares for division during the G1 phase. During the G1 phase, cells are extremely metabolically active.
