MicroGenie can compare two sequences to detect regions of homology between them and can align two or more sequences, inserting gaps if necessary to improve the alignment. The procedures to do this are in the Compare section. A sequence (DNA or protein) can be searched for homologies against a data bank or against specified sequences. The Data Bank section of MicroGenie contains the procedures to search the data banks and to retrieve specified sequences from the data bank CD-ROM by author or keywords.
