 This program discusses how the chemical alteration of oncogenes in human cells causes the growth of cancerous tumors. Toxic substances, radiation, viruses, and inherited genetic defects are examined as factors causing such alteration. The mechanisms by which the altered forms overrule normal cell regulation are illustrated through microscope views and computer animation. Specific information is provided on cell cycle, cell division, growth factors, receptors, protein kinase, phosphatase, G-proteins, transduction processes,
src-, ras-, and raf-oncogenes, and signal transduction. (33 minutes)

Viruses
Viruses are the simplest forms of life-so primitive in biological terms that for some years the scientific community debated whether they should even be regarded as living organisms. This program examines how viruses, though incapable of reproducing ...(more details) |
