NEET BIOLOGY

Detailed explanation-1: -Gap 1 (G1): during this phase, the cell grows rapidly, while performing routine metabolic processes. It also makes proteins needed for DNA replication and copies some of its organelles in preparation for cell division. This phase is sometimes referred to as Growth Phase 1.

Detailed explanation-2: -During the G1 phase, the cell is metabolically active and requires many organelles for protein synthesis, while acquiring the potential for the DNA doubling process.

Detailed explanation-3: -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-4: -In G1, cells accomplish most of their growth; they get bigger in size and make proteins and organelles needed for normal functions of DNA synthesis. Here, proteins and RNAs are synthesized, and, more especially the centromere and the other components of the centrosomes are made.

Detailed explanation-5: -Answer and Explanation: The metabolic or growth phase of a cell’s life cycle is called interphase. Metabolic processes in the body that are related to growth of the cell and its life cycle all occurs during the interphase.
