Web3 days prior to performing the chromosome spreads. 2. Feed cells with fresh media 12-14 h prior to harvesting. 3. Add Colcemid to a final concentration of 0.02 µg/ml; incubate at 37 °C for a 3-4 h. 4. Transfer the medium to a centrifuge tube and rinse the flask with 1.5 ml PBS (without Ca. 2+ and Mg. 2+). Detach the cells with 0.5 ml of trypsin. WebThe short answer is: to make sure that, during cell division, each new cell gets exactly one copy of each chromosome. For a more satisfying answer, check out the articles and videos on the cell cycle and mitosis. There, you can see how the behavior of chromosomes helps cells pass on a perfect set of DNA to each daughter cell during division.
