WebChromosomes are made of strands of DNA wrapped around spools of protein called histones and organized into distinct packets. The packets are accessible for copying in the cell and are transportable. When a cell splits to make two new cells, a copy of each chromosome can be moved into each of the newly forming cells. WebThe chromosomes - and the DNA they contain - are copied as part of the cell cycle, and passed to daughter cells through the processes of mitosis and meiosis.
