SnapGene is a professional molecular biology software designed to help researchers plan, visualize, document, and analyze DNA sequences and molecular biology workflows. It provides tools for DNA sequence editing, plasmid mapping, annotation, cloning simulation, PCR planning, primer design, and sequence alignment.
The software can display DNA in circular or linear maps and allows users to customize the appearance of enzyme sites, features, primers, ORFs, and other sequence elements. It can also handle large DNA sequences containing thousands of annotated features.
SnapGene is designed for researchers, molecular biologists, students, and laboratory professionals who need an integrated environment for DNA sequence analysis and cloning workflows.
