    Abstract: Provided are a method and a device for synthesizing proteins from DNA molecules captured in microchambers, whereby the distance between microchambers can be shortened, thereby allowing the density of arrays to be increased. Microchambers (32) are arranged at a high density. A DNA solution (34) which has been diluted so as to capture one DNA molecule on average is enclosed in the microchambers (32). Then, mRNA is synthesized using one DNA molecule on average as a template. Based on this mRNA, a protein (37) is extracellularly synthesized.

The program management unit causes an allowed program or process to be executed based on a result of determination as to whether the program or process to be executed in a host terminal is allowed to gain access. The IP management unit causes data to be transmitted to an allowed destination IP address based on a result of determination as to whether the destination IP address to which the host terminal attempts to transmit the data is allowed to be accessed. The encryption processing unit encrypts and decrypts all data, exchanged between the host terminal and the hard disk by applying an algorithm, selected by a user, to the data.
