- Through cloning and sequence analysis, researchers have identified the primary gene of the hereditary disease muscular dystrophy, thus leading to the characterizing of the primary protein product. Deletions contributing to an absence of the polypeptide dystrophin (0.002% of total muscle protein and 3,685 amino acids long) on the inner surface of the plasma membrane appear to be the primary cause for two types of muscular dystrophy. The polypeptide may play cytoskeletal roles, since it is sequence-related to spectrin and à-actinin.

  • Biological light emission (cold light, bioluminescence) has had a "gee-whiz" attraction for humans since the days of the ancient Greeks. New recombinant DNA technology for "gene fusions" and the use of the bioluminescence...
