Science Image (image) Salk Institute Caption This image shows telomeres (yellow), protective caps on the ends of chromosomes, moving to the outer edge of a cell's nucleus (blue). Salk researchers found that the telomeres anchor to the nuclear envelope after the cell duplicates its DNA during division, which may help organize the chromosomes as the cell splits into two daughter cells.
