Chromomere function
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. WebApr 28, 2024 · Chromatid Definition. When a cell is preparing to divide, it makes a new copy of all of its DNA, so that the cell now possesses two copies of each chromosome. The two copies of the cell’s original chromosome are called “sister chromatids.”. During anaphase of cell division, the two chromatids will be pulled apart, and chromatid will be ...
