NEET BIOLOGY

Detailed explanation-1: -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-2: -There are three stages of interphase: G1 (first gap), S (synthesis of new DNA ), and G2 (second gap). Cells spend most of their lives in interphase, specifically in the S phase where genetic material must be copied. The cell grows and carries out biochemical functions, such as protein synthesis, in the G1 phase.

Detailed explanation-3: -The Interphase of the eukaryotic cell cycle can be subdivided into the following phases (Figure 7.2. 2). Growth Phase 1 (G1): The cell spends most of its life in the first gap (sometimes referred to as growth) phase, G1. During this phase, a cell undergoes rapid growth and performs its routine functions.

Detailed explanation-4: -The interphase is the longest phase of the cell cycle because it is the stage during which all the preparation for cell division takes place.
