A multifunctional base sequence method largely shortens the calculation time and reduces the volume of memory consumption of a processor by carrying out calculation with the advance exclusion of base sequences in which translation termination codons emerge in the second and third reading frames, which are to be excluded in the end. A copper plating method wherein the object to be plated and a pre-treatment solution in which bromide compound ions are contained are brought into contact and copper is precipitated by means of electrical plating using a copper plating solution. The obturator is used notably for sealing closing an opening in a motor vehicle body. The auto-on conductor causes the meter to wake up and perform a test strip sequence when the test strip is inserted in the meter.
