NEET BIOLOGY

Detailed explanation-1: -Interphase is a non-dividing phase that includes G1, S and G2 phases. During the G1 phase, the cell grows in size and synthesizes the cellular contents. Cells in the G1 phase do not divide, rather make preparations to divide. DNA replicates in S phase and overall cell growth is observed in G2 phase.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -Prophase. Mitosis begins with prophase, during which chromosomes recruit condensin and begin to undergo a condensation process that will continue until metaphase.
