At a Glance

The Essentials of Cellular Reproduction: Cell division transmits a complete set of hereditary information to each daughter cell.
Cell division transmits essential cytoplasmic materials to each daughter cell.
The activities of a cell from one cell division to the next constitute the cell cycle.

Prokaryotic and Eukaryotic Chromosomes Compared

The Prokaryotic Cell Cycle

The Eukaryotic Chromosome
The eukaryotic chromosome consists of a single strand of DNA complexed with proteins.
Eukaryotic chromosomes often occur in pairs containing similar genetic information.

The Eukaryotic Cell Cycle
Growth, replication of chromosomes, and most cell functions occur during interphase.
Cells vary in the duration of interphase.
Cell division consists of nuclear division and cytoplasmic division.

Mitosis
During prophase, the chromosomes condense and the spindle apparatus forms and attaches to the chromosomes.
During metaphase, the chromosomes are aligned along the equator of the cell.
During anaphase, sister chromatids separate and are pulled to opposite poles of the cell.
During telophase, nuclear envelopes re-form around each group of chromosomes.

Cytokinesis

Cell Division and Asexual Reproduction; Cell division transmits essential cytoplasmic materials to each daughter cell.
The activities of a cell from one cell division to the next constitute the cell cycle.
