This program discusses the development, organization, and functions of the nervous system and the input organs that stimulate it. Beginning with an introductory overview of neural anatomy, the video outlines the organization of the central and peripheral nervous systems and the processes of sensation, transduction, and perception. In addition, the senses of vision, hearing, taste, smell, and equilibrium are analyzed, as well as sensitivities to temperature, pressure, and pain; bodily movement via the somatic neurons is illustrated; and the neural mechanics of sleep and wakefulness are considered.

Biochemistry DVD begins by describing the basic structure of atoms and how ions are formed as atoms gain or lose electrons. Molecules and the covalent bonds that hold them together are then investigated. The program then explains the difference between organic and inorganic molecules, polar and non-polar molecules and how the hydrogen bonds that form between polar H2O molecules provide water with a number of unique characteristics critical to life. A look at the concept of pH and the role of buffers concludes the program.

Biochemistry DVD starts by explaining how polymers are synthesized out of smaller monomers through dehydration reactions that release H2O molecules in the process. The program goes on to look at the role of carbohydrates in energy storage and as structural building blocks; the use of lipids in synthesizing plasma membranes, fats and steroid hormones; proteins in their role as enzymes, hormones, and structural materials; and nucleic acids use in storing information and transferring energy.

Biotechnology DVD first looks at major research areas in biotechnology such as the Human Genome Project and the various forms of recombinant DNA technology that produce transgenic plants and animals. The program then goes on to look at the tools used by biotechnologists such as restriction enzymes, plasmids, vector and vector less insertion of genes into genomes, and the production of genes via polymerase chain reactions. The program then concludes by looking at the future of biotechnology and some of the environmental, economic, and ethical issues raised by biotech.

Cell Membranes DVD begins by examining cell wall structure and the major functions of cellular membranes before introducing the fluid mosaic model of the phospholipid bilayer, and transport, recognition, and receptor proteins. The concepts of simple and facilitated diffusion, passive and active transport, and osmosis are illustrated. Endocytosis and exocytosis, the role of contractile and central vacuoles, and how desmosomes and tight junctions tie cells together and how plasmodesmata and gap junctions facilitate communication are explained.

Cell Structure DVD first explains the difference between prokaryotic and eukaryotic cells and then explores in detail the structure and function of the major organelles found in eukaryotic cells. Examined organelles include: the nucleus, ribosomes, smooth and rough endoplasmic reticulum, the Golgi complex, lysosomes, chloroplasts, mitochondria, plastids, contractile and central vacuoles, cilia, flagella and the microtubules, microfilaments, and intermediate filaments that make up the cytoskeleton. The program concludes by looking at how cellular shape varies with cellular function.

Mitosis Video starts by introducing the cell cycle and briefly describing the process of binary fusion in prokaryotic cells before going on to a detailed look at the eukaryotic cell cycle from the G1, S and G2 phases of interphase through the prophase, metaphase, anaphase and telophase phases of mitosis. The difference between cytokinesis in animal and plant cells is then illustrated. The program concludes by explaining why an understanding of cellular division is critical to: conquering cancer, cloning organs, and perhaps even reversing aging.

DNA DVD looks first at the structure of DNA before going on to describe how DNA carries out its four major functions: the storage of information; the replication of information; creating slight changes in the information through mutations that forces of natural selection act upon; and the translating of information into the proteins that define an individual. During this discussion students are introduced to: point mutations; insertions and deletions; the genetic code; transfer, messenger, and ribosomal RNA; and the process of replication and translation.
