Chromosomes lined up for cell division ​

This cell is preparing to divide. Two copies of each chromosome (blue) are lined up next to each other in the center of the cell. Next, protein strands (red) will pull apart these paired chromosomes and drag them to opposite sides of the cell. The cell will then split to form two daughter cells, each with a single, complete set of chromosomes.
