Detailed explanation-1: -During mitotic prophase, the chromatin condenses, becoming more visible (chromatin condensation). The chromatin fibers condense to become distinct chromosomes that are visible when viewed under the light microscope at high magnification. Spindle formation begins and the nucleolus seems to disappear.
Detailed explanation-2: -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-3: -The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA.
Detailed explanation-4: -The G1 phase, gap 1 phase, or growth 1 phase, is the first of four phases of the cell cycle that takes place in eukaryotic cell division. In this part of interphase, the cell synthesizes mRNA and proteins in preparation for subsequent steps leading to mitosis.
Detailed explanation-5: -During metaphase, all of the chromosomes are aligned in a plane called the metaphase plate, or the equatorial plane, midway between the two poles of the cell.
