Abstract: The present invention broadly comprises a storage system comprising a plurality of rungs serving as hangers or for supporting hanging devices. The rungs are spaced vertically along a pair of elastic cords that are hooked, top and bottom to a rectangular shaped support, such as a door.

Abstract: A combination toilet implement and holder therefor includes an implement handle having first and second handle ends, a handle intermediate portion between the first and second handle ends, and a shield retaining structure. An implement head is provided attached to the handle proximate the second handle end. A shield is provided that at least partially surrounds the handle intermediate portion. The shield has first and second shield ends in turn having first and second shield openings respectively. The first shield opening is oriented toward the first handle end and the second shield opening is oriented toward the second handle end and is sized so as to be capable of surrounding the implement head. The shield is movable along the handle toward the implement head so as to at least partially surround the implement head and so as to be movable along the handle away from the implement head so as to be engaged with the retaining structure to prevent the shield from falling over the implement head during use.

Abstract: The invention provides compositions and methods for performing primer extension reactions, including employment of amplification primers having 5′ tags to incorporate into amplicons variant nucleotides of interest from target nucleic acids at known ratios, with or without sequences surrounding the variant nucleotides of interest. The invention provides identifying the variant nucleotides generated from the target nucleic acid and generated from the 5′ tags, comparing the results, evaluating the efficiency of the primer extension reactions, and monitoring the efficacy of such reactions. The invention accounts for DNA sequence and experimental variables that may affect efficiency of incorporation of nucleotides, and provides a reference point for the interpretation of polymorphisms. The invention also provides methods of breeding scrapie-resistant sheep populations.
