Abstract: Presented herein are altered polymerase enzymes for improved incorporation of nucleotides and nucleotide analogues, in particular altered polymerases that maintain low error rate, low phasing rate, or increased incorporation rate for a second generation ffN under reduced incorporation times, as well as methods and kits using the same.

Abstract: A compound power generating system comprises a housing unit, a power unit, a rotation unit, at least one oxyhydrogen generating unit and a combustion unit. In the present invention, the collected solar energy is transformed into electric energy to drive the oxyhydrogen generating unit to generate fuel gas, and then the combustion unit burns the fuel gas to generate the updraft air to cause the fans to drive the kinetic generator to generate electrical energy. Therefore, the solar energy is indirectly transformed into the mechanical kinetic energy to drive the kinetic generator.
