GEL--a computer tool for DNA sequencing projects.

The GEL program for entry and analysis of DNA sequencing information is discussed, and examples of interaction with the program are presented. The current version of the program represents the last of several revisions to the first GEL program, reported previously in this journal (1). Improvements and additions have been made, making the current GEL a particularly useful laboratory tool for molecular biologists engaged in DNA sequencing projects.
