Disclosed are improved methods of making and using immobilized arrays of nucleic acids, particularly methods for producing replicas of such arrays. A related electronic device is also provided. When a request device 1 issues a direct transfer request to directly transfer data to or from a data storage unit 24 included in the response device 2, the response device 2 performs control so that data is directly transferred between a communication unit 23 and the data storage unit 24. A plurality of support legs and guide plates are installed between the upper and base plate, and the support legs and guide plates may be integrally formed on the lower side of the upper plate or may be separately produced to be assembled with the upper plate. The present invention also discloses the use of such polynucleotide encoding protein P125-77.
