Question

Differentiate between prophase and metaphase

Answer 1

At the start of prophase, the chromosomes condense and can now be seen under a microscope. The nucleus will disappear, freeing the chromosome pairs. The centrioles begin to migrate toward the far ends of the cell while the mitotic spindle forms. Spindle fibers from each side of the cell attach to one side of each chromosome pair.

Between prophase and metaphase, prometaphase happens. At this time, proteins wrap around the center of the chromosomes to make kinetochores. During metaphase, the spindle fibers move the chromosome pairs to the center of the cell in alignment. This is a vitally important step in the process of cell division. If the chromosome pairs are not lined up properly, the daughter cells won't receive only one copy of each chromosome. This could potentially lead to genetic defects in the cell.

Answer 2

During prophase double stranded chromosome become visible and nuclear membrane surrounding them disappear

During metaphase the centromere of double stranded attach to spindle fibre.the chromosome move toward middle of cell and lined up at cell equator
