Magenta (DNA) and green (lysosome) fluorescent markers indicate that cells eject waste products from the cell before late mitosis.
Science Snapshot: Mitotic Housekeeping
Researchers reveal that a measurable drop in the dry mass of a cell prior to mitosis is caused by waste products being jettisoned before the cell divides.
