This enhanced DVD film uses animation to explain cellular growth from birth to death and the intermediary phases that occur. It is an easy to understand presentation of the intricate cellular processes including the cell division of mitosis and the creation of cellular structures during cytokinesis.
The film explains how DNA participates in the duplication of chromosomes after the nucleus divides to make a copy of itself. It shows how during prophase the nucleus gets a signal that triggers the process, which begins chromosome replication. Two growth phases called gaps and the synthesis phase are explained in detail. It shows how centrosomes make spindle fibers to hold everything together and how DNA stimulates the production of lysosomes.
In the metaphase, all the chromosomes attach to the spindle fibers and line up properly. Following this is the anaphase where chromosomes are pulled apart. Next, comes the telephase where the nucleus is reformed and attachment of the spindle fibers occurs. Meiosis is the process of sexual reproduction where the male and female gametes meet and each one loses half of their DNA to create more diversity in genetic transmission to their offspring.
Finally, there is an explanation of apoptosis, which is a pre-programmed cellular death that ends the cell's life cycle. This is the natural course of cell life and death. When the process is distorted and apoptosis does not occur as it should, these are cells that grow out of control, which cause cancer.
All of these processes combine in unique ways as part of the cell growth pattern and reproduction.
