Computer support of DNA sequence analysis.

The paper describes a package of APL-programs suited for the management and the analysis of DNA sequence data. Most of the application programs are related to experimental work in a DNA sequencing laboratory: Search for overlapping DNA fragments to construct complete DNA sequences; search for restriction sites; computing fragment patterns when cutting a DNA with restriction enzymes; plotting physical and genetic maps of a DNA; search for homologies as well as various counting procedures. More sophisticated programs are concerned with the prediction of RNA secondary structure and its graphical representation.
