![]() Results revealed significant gains in both comprehension and production for subjects in processing instruction, while subjects in traditional instruction had significant gains only in production. Pretest and posttest measures consisting of one interpretation (comprehension) and one production task were submitted to a Multivariate Analysis of Variance. Publication types Research Support, N.I.H. The protein is a member of the DDE/D subfamily of transposases a very large class of enzymes responsible for the movement of DNA segments from one region to another and are considered some of the most ubiquitous genes found. The results define the series of stable nucleoprotein complexes that mediate retroviral DNA integration. Integrase (IN) is a nucleic-acid-processing enzyme present in retroviruses that is critical for viral propagation. Sixty-one classroom learners of Spanish were assigned to one of three instructional treatments: traditional instruction, processing instruction, and no instruction. The integration product also remains stably associated with integrase and likely requires disassembly before completion of the integration process by cellular enzymes. In addition, the terminal nucleotide requirements for concerted integration are more stringent than for the half-site reaction. in cooperation with NATO Scientific Affairs Division. Traditional instruction involved grammar explanation and output-based practice, while processing instruction involved grammar explanation and input-based practice aimed at redirecting learners'strategies in processing input data. The reaction pathway is channeled to concerted integration, and half-site integration products are reduced with blunt-ended DNA substrate that must first be processed by integrase. Batch processing systems engineering: current status and future directions proceedings of the NATO Advanced Study Institute on Batch Processing Systems Engineering: Current Status and Future Directions, held in Antalya, Turkey, May 29 - J/ ed. The present study extends previous research (VanPatten & Cadierno, 1993a, 1993b) and compares the relative effects of two types of instruction (i.e., traditional instruction and processing instruction) on the acquisition of Spanish past tense verb morphology.
