The GenBank Search is a Macintosh Hypercard stack for interacting with the computer services from Genbank at NCBI. These free search and fetch services thru electronic mail include: * Searching of the current GenBank, or several other databanks, for similarities with a query nucleic acid or protein sequence of yours, and * Retreival of a sequence in the current GenBank by keywords, locus name or accession number. Several other databanks are also available for retreival. To use this GenBank Search stack, you must have: -- a Macintosh with Hypercard version 2, and Mac System 6.0.5 or later, -- that Mac needs to be connected to the national Internet network, thru an Appletalk or Ethernet cable, -- that Mac must have the MacTCP communications software, and Hypercard version 1.2 or later, from Apple Computer, -- you must have a valid Internet return mail address.
