Abstract: It is intended to provide a primer having a promoter region added thereto; and a method of using the primer having a promoter region added thereto in RNA amplification, gene expression analysis and/or identification analysis of an organism. A primer is constructed by adding a promoter region to a random primer capable of binding to a part highly complementary to an RNA or a primer containing a base sequence complementary to a specific gene. Then, the obtained primer is employed in RNA amplification, gene expression analysis and/or identification analysis of an organism.

Abstract: A single-phase clock and an output signal of a second delay circuit are inputted to a first NAND gate and a first NOR gate. The output signal of the first NAND gate is inputted to a gate of a first PMOS transistor of a first clock driver. The output signal of the first NOR gate is inputted to a gate of a first NMOS transistor of the first clock driver. Meanwhile, an inverted clock outputted from an inverter and an output signal of a first delay circuit are inputted to a second NAND circuit and a second NOR circuit. The output signal of the second NAND gate is inputted to a gate of a second PMOS transistor of a second clock driver. The output signal of the second NOR gate is inputted to a gate of a second NMOS transistor of the second clock driver.
