A general DNA analysis program for the Hewlett-Packard Model 86/87 microcomputer.

A program is described to perform general DNA sequence analysis on the Hewlett-Packard Model 86/87 microcomputer operating on 128 K of RAM. The following analytical procedures can be performed: 1. display of the sequence, in whole or part, or its complement; 2. search for specified sequences e.g. restriction sites, and in the case of the latter give fragment sizes; 3. perform a comprehensive search for all known restriction enzyme sites; 4. map sites graphically; 5. perform editing functions; 6. base frequency analysis; 7. search for repeated sequences; 8. search for open reading frames or translate into the amino acid sequence and analyse for basic and acidic amino acids, hydrophobicity, and codon usage. Two sequences, or parts thereof, can be merged in various orientations to mimic recombination strategies, or can be compared for homologies. The program is written in HP BASIC and is designed principally as a tool for the laboratory investigator manipulating a defined set of vectors and recombinant DNA constructs.
