WebTelomeres protect chromosomes during DNA replication. By keeping our DNA secure, chromosomes make daily activities possible. For an organism to function properly, certain cells must constantly divide and replace older worn out cells with new ones. Chromosomes allow DNA to be accurately copied during these cell divisions. So one more time. WebA quick overview. Chromosomes are bundles of tightly coiled DNA molecules. In eukaryotic cells, chromosomes are stored in the nuclei of cells. We have 23 pairs of chromosomes (1-22, X, and Y), and the number will double right before the cell division. When cells are ready for division, their long DNA threads will be compressed into chromosomes.
