    摘要: A method for inserting a cassette into a nucleic acid molecule to produce a modified nucleic acid molecule, e.g., a nucleic acid-cassette fusion, is described. The method involves the use of polymerase chain reaction, thereby permitting precise targeting of the desired site in the molecule, but does not require ligation. Also described is the use of this method for high throughput screening the resulting modified nucleic acid molecules.

    摘要: A method and apparatus for counting irregularly-shaped articles. A pair of light sources are provided at a sensing plane through which articles to be counted are adapted to pass. Each of the light sources emits a light beam that is at an angle to the other light beam, such as an angle of about 90.degree.. Corresponding solar cells are positioned opposite the respective light sources to receive the light signals as the articles pass through the sensing plane. The light sources are alternately operated and the outputs from the respective light detectors are used to calculate an equivalent volume for the article for comparison with a predetermined article volume range to decide whether to count the article. The method and apparatus permit accurate counts of irregularly shaped articles and are substantially independent of the orientation of the article at the sensing plane.
