摘要:
A method of characterizing an unknown organism species comprises determining the position of part or whole of evolutionarily conserved sequences in genetic material of said organism, relative to a known position of restriction endonuclease cleavage sites in said genetic material (other than by determining the chromatographic pattern of retriction endonuclease digested DNA from said unknown organism, which digested DNA has been hybridized or reassociated with ribosomal RNA information containing nucleic acid from or derived from a known probe organism), thereby to obtain an identifying genetic characterization of said unknown organism, and comparing said characterization with information from at least two sets of identifying genetic characterizations derived from the same conserved sequences, each of said sets defining a known organism species.

Un appareil et un procédé permettent l'affichage et la visualisation d'images stéréoscopiques sur un champ de vision total. L'appareil comporte des composants d'affichage droit et gauche (12) comprenant des écrans incurvés (14). Ces écrans se montent dans une position fixe par rapport à la tête de l'observateur et à proximité de ses yeux. Lesdits écrans assurent le champ de vision total monoculaire normal de 120° verticalement et 180° horizontalement. Chaque écran (14) présente une surface centrale sphérique et une surface temporale cylindrique qui s'étend depuis la surface centrale en suivant le côté de la tête de l'observateur. Les écrans sont montés à proximité des yeux de l'observateur, et des composants optiques sont prévus pour amener les yeux de l'observateur à se focaliser au niveau de la surface centrale. Des lentilles de contact (22) constituent des composants optiques appropriés. Les lentilles de contact ne limitent pas le champ de vision de l'observateur et s'orientent en continu avec les mouvement des yeux de ce dernier.

A method of detecting a prokaryotic organism comprises selectively hybridising the DNA of the prokaryotic organism with a detectably labeled prokaryotic ribosomal RNA-information-containing hybridisation probe.
摘要:
A method of characterizing and/or identifying an unknown organism which comprises comparing the chromatographic pattern of restriction endonuclease-digested DNA from the organism, which digested DNA has been reassociated or hybridized with ribosomal RNA-information containing nucleic acid from a probe organism, with equivalent chromatographic patterns of at least two known different organism species.
