WebDNA is packaged in a chromosome. Higher cells incorporate an ancient chromosome. Some DNA does not encode protein. Some DNA can jump. Genes can be turned on and off. Genes can be moved between species. DNA responds to signals from outside the cell. Different genes are active in different kinds of cells. Master genes control basic body plans. WebThe final packaging occurs when the fiber is organized in loops, scaffolds and domains that give a final packing ratio of about 1000 in interphase chromosomes and about 10,000 in mitotic chromosomes.
