The DNA Molecule and Its Role in the Cell
All living organisms are made up of cells, some organisms are single cells, others are formed from millions of cells. Two types of cells are commonly identified by the group names prokaryotes and eukaryotes. The eukaryotes are probably a more complicated form of cell life, which has evolved from the prokaryotes. The eukaryotes are distinguished from the prokaryotes, because they have evolved a nuclear envelope, which separates the nucleus from the rest of the cell, a nucleolus in the nucleus and a spindle which assists in the organization of the chromosomes through cell division.
