Abstract: The object of the present invention is to provide a genome information display system that allows the user to quickly conduct operations such as movement of display content on the screen presenting information of a gene or the like of a genome. A server 10, on receipt of a request for map screen from a terminal 60, transmits, to the terminal 60, a mass of map screen data necessary for preparing a map screen. Therefore, for example, when the user conducts operations such as movement, expansion/contraction of the display extension of an enlarged map on a map screen, the terminal 60, instead of making a renewed access to the server 10 for data communication, quickly prepares an enlarged map presenting the display extension according to the operation, based on the mass of map screen data stored in the memory means of the terminal 60, and displays the enlarged map at a high speed matched with the user's operation.
