Which of the following best describes the relationship between a cell’s nuclear membrane and chromosomes during prophase and metaphase? A Once the nuclear membrane completely disappears, chromosomes are able to line up along the center of the cell. B The nuclear membrane carries chromosomes from their original position to the center of the cell as metaphase occurs. C As chromosomes disappear, the nuclear membrane recreates new chromosomes that line up along the center of the cell. D The nuclear membrane splits and moves to either side as spindle fibers extend to connect to chromosomes along the center of the cell.
