Abstract: The present invention comprises an apparatus for attachment to the rotatable vertical elevation adjuster used on vertically adjustable bow sights. The bow sight ancillary distance marker attachment provides a semi-smooth surface on the exterior to attach a tape for elevation markings that corresponds to a particular projectile's unique characteristics. The bow sight ancillary distance marker attachment is secured with a set screw inserted into an opening with molded threading corresponding to the thread size and pitch of the set screw; or when manufactured from pliable material the bow sight ancillary distance marker attachment is held in place by friction.

Abstract: DNA sequences from potato which encode the enzyme solanidine UDP-glucose glucosyltransferase (SGT) are disclosed. Recombinant DNA molecules containing the sequences, and use thereof, in particular, use of an antisense DNA construct to inhibit the production of SGT and thereby reduce glycoalkaloid levels in solanaceous plants, e.g., potato, are described.
