Document Summary
Ability of living organisms to produce cells distinguishes them from non-living things. The continuity of life is based on cell division. Cell division also replaces dying cells in eukaryotes, renewing them. Cell division is an integral part of the cell cycle, from the time it first formed during division of the parent"s cell to the time it divides on its own into two daughter cells. Passing genetic information to an offspring cell is very crucial. Most cell division leads to genetically identical daughter cells: In prokaryotes and eukaryotes most cell division involves distribution of genetic material to two daughter cells. The fidelity of dna passed down is notable as a dividing cell replicates its dna, allocates two copies to opposite ends of the cell, splits into two daughter cells. Cells endowment of genetic information (dna) is called its genome. Prokaryotes have a single dna; eukaryotes have multiple dna molecules.
