Inside the living cell: the outer envelope
Here students become acquainted with the properties of the plasma membrane, how it governs the kinds of molecules that go in and out of cells, and how cells feed by engulfing (phagocytosis) and drink in fluids by pinocytosis. Content: Membrane Struc...
Inside the living cell: how cells are controlled
This program describes the genetic code, and how genetic instructions carried on DNA are transcribed into RNA. Explains how genes dictate enzymes and how enzymes produce specific reactions in cell processes. This highly visual tour of the processe...
Inside the living cell: how cells reproduce
This program discusses how DNA replicates, how copy errors occur and are remedied by repair enzymes, and how DNA is compressed into chromosomes making possible mitosis and cell division. This highly visual tour of the processes that keep life opera...
Visualizing cell processes: cell movement and transport
Topics: Structure and Behavior of the Plasma Membrane, Osmosis, Transport Proteins, Phagocytosis, Pinocytosis, Receptor Mediated Endocytosis, Golgi Function, Lysosomes and Hydrolytic Digestion, Microtubules, Cilia, Actin, and Myosin Motor Proteins.
Visualizing cell processes: photosynthesis and cellular respiration
Through live action and animated models, this program illustrates the basic biochemical processes involved in photosynthesis and cellular respiration. Cellular Respiration Topics: Glycolysis and Fermentation, Mitochondrion Structure, Aerobic Respira...
Branches on the tree of life: the biology of chordates
The Phylum Chordata includes tunicates, sea lancelets, hagfish, and all familiar vertebrate animals. This program explores how these seemingly diverse animals evolved and how the group is unified by four characteristic structures: a hollow dorsal ne...
Branches on the tree of life: the biology of annelids
Worms with segmented bodies make up the Phylum Annelida. This program explores the three classes of annelids: Class Polychaeta (feeding, locomotion, and larval stages), Class Oligochaeta (lifestyles, feeding adaptations, and anatomy of freshwater o...
Visualizing cell processes: DNA replication, mitosis and cell reproduction
Topics: Chromosome Condensation, Mitosis Stages, Cytokinesis, Meiosis, Nucleotide Structure and Bonding, Replication Enzymes, Replicating the Strands, Topoisomerase and the Twisting Problem, Proofreading and Repair, Replication Review.
Visualizing cell processes: the genetic code and its translation
Topics: The Protein Nature of Life, Protein Structure, Transcription, Translation and Protein Synthesis, Gene Regulation in Prokaryotes, Exons and Introns, Mutations, Renegade DNA - The Viruses.
