Detailed explanation-1: -Prophase immediately follows the S and G2 phases of the cycle and is marked by condensation of the genetic material to form compact mitotic chromosomes composed of two chromatids attached at the centromere.

Detailed explanation-2: -Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.

Detailed explanation-3: -Prophase-the first stage of mitosis. Spindles attached to kinetochores begin to shorten. This exerts a force on the sister chromatids that pulls them apart. Spindle fibers continue to shorten, pulling chromatids to opposite poles.

Detailed explanation-4: -Metaphase follows prophase. During metaphase, the chromosomes align in the center of the cell at the equatorial plate and the spindle fibers attach to the centromeres of the chromosomes.

Detailed explanation-5: -Prophase occurs in mitosis, and prophase I occurs in the first division of meiosis, meiosis I. Prophase II occurs in the second division of gametic cells, and is distinguished by the chromosomes condensing and the centrosome dividing to either side of the cell.
