A DNA analysis program designed for computer novices working in an industrial-research environment.

Area of Science:

• Bioinformatics
• Computational Biology
• Molecular Biology

Background:

• DNA sequence analysis is crucial in molecular biology.
• Existing tools often require significant computer expertise.
• There is a need for accessible DNA analysis software.

Purpose of the Study:

• To describe a user-friendly DNA sequence analysis program.
• To meet the needs of researchers with limited computer backgrounds.
• To facilitate efficient DNA analysis on personal computers.

Main Methods:

• Developed a program prioritizing user-friendliness and low storage requirements.
• Utilized FORTRAN 77 for broad compatibility.
• Implemented modular subprograms controlled by an executive.
• Created a file management system with 'SEQ' and 'SITE' files for organizing DNA sequences and search patterns.
• Incorporated color graphics for enhanced visualization.

Main Results:

• The program successfully handles large DNA files (>10 kilobases).
• It requires minimal storage, suitable for IBM personal computers.
• The file management system allows for categorized searching of DNA sequences (e.g., restriction enzyme sites within plasmid sequences).
• All necessary DNA analysis tasks are supported.

Conclusions:

• The developed program effectively democratizes DNA sequence analysis.
• It empowers researchers without computer expertise to perform complex analyses.
• The software offers a practical solution for managing and analyzing large DNA datasets efficiently.
