... Individual genes of DNA can be copied into mRNA. All DNA on a chromosome is copied before the cell divides. Now instead of one pair (times 23) of chromosomes, we have two pairs (times 23). 1) The chromosomes are copied. 2) The cell’s nuclear membrane disappears. 3) Two organelles called centrioles m ...
