X-ray fiber diffraction studies of satellite DNAs from Gecarcinus lateralis, Drosophila virilis and Mus musculus, all of which have highly repetitious base sequences but with different degrees of sequence complexity, reveal only classical polynucleotide duplex structures in contrast to some highly repetitious synthetic DNAs.

A survey was conducted by the Department of Medical Technology at Wayne State University to determine current admission procedures for student selection. With more applicants applying for clinical education than can be accepted, the selection process becomes critical. Questionnaires were sent to institutions throughout the United States with accredited programs in medical technology. Among the findings, trends indicate the use of grade point average, separate evaluation of science grades, use of an admissions committee, and a dependence on references and transcripts in selecting students. In addition, the study shows that in all the accredited programs surveyed, including universities, hospitals, Veterans Administration hospitals, and others, an average of 82 students apply each year for the 15 available positions, a ratio of 5.5:1.

A combination of both Ag(+) and Hg(2+) in Cs(2)SO(4) effects the complete separation of two DNAs having identical densities in CsCl. Satellite DNAs of hermit crab, Pagurus pollicaris, and lobster, Homarus americanus, have been isolated by this means.

If the Bermuda land crab, Gecarcinus lateralis, loses numerous walking legs or both chelipeds, it undergoes almost immediate preparations for molting with attendant limb regeneration. Injections of the arthropod-molting hormone, ecdysterone, have no effect in either intact animals or those missing legs.
