Information processing system using nucleotide sequence-related information

A system for processing information for providing semantic information and/or information associated with the semantic information useful for each individual organism through effective utilization of differences in nucleotide sequence-related information among individual organisms is constructed. The method for processing information on a nucleotide sequence comprises: (a) receiving request information for an object and/or service; (b) obtaining positional information in accordance with the request information from a memory having positional information representing a position in a nucleotide sequence memorized therein; and (c) obtaining nucleotide sequence-related information corresponding to the positional information obtained in (b) above, and obtaining semantic information implied by the nucleotide sequence-related information and/or information associated with the semantic information.
