Concept 12.1 Cell division results in genetically identical daughter cells. Cell division requires the distribution of identical genetic material—DNA—to two daughter  cells. The special type of cell division that produces sperm and eggs results in daughter cells that are  not  genetically identical. What is remarkable is the fidelity with which DNA is passed along, without dilution, from one  generation to the next. A dividing cell duplicates its DNA, allocates the two copies to opposite ends of the cell, and  only then splits into daughter cells. A cell’s genetic information, packaged as DNA, is called its  genome . In prokaryotes, the genome is often a single long DNA molecule. In eukaryotes, the genome consists of several DNA molecules. A human cell must duplicate about 2 m of DNA and separate the two copies so that each  daughter cell ends up with a complete genome. DNA molecules are packaged into
