This is professional software for molecular biology that allows you to design, document, and visualize DNA experiments. Unlike manual diagrams and traditional approaches, the program allows you to simulate molecular cloning in advance, verify the correctness of primer design, perform PCR simulation, and even virtually reproduce agarose gel simulation. This approach saves laboratory resources, reduces errors, and makes DNA sequence analysis more transparent and predictable.
Key features
Support for popular cloning strategies (molecular cloning, Gibson Assembly, restriction cloning, Golden Gate, Gateway).
Tools for primer design and primer parameter analysis (Tm, GC%) with off-target prevention.
Realistic PCR simulation with the ability to model different scenarios — from standard reactions to multiplex.
Agarose gel simulation: virtual display of expected bands and verification of fragment accuracy.
Visual plasmid mapping and work with plasmid files in circular and linear formats.
Flexible sequence annotation and feature detection for automatic marking of coding sequences, promoters, and ORFs.
Restriction enzyme database support and enzyme configuration based on specificity.
Tools for site-directed mutagenesis, reading frame analysis, and mutation verification.
Support for multiple formats (GenBank, FASTA, EMBL, etc.) — broad file format compatibility.
Sequence comparison and sequence alignments for quick matching.
Visualization of secondary structure prediction for single-stranded regions.
Graphical history of changes with detailed version tracking.
Bulk actions and advanced search for managing project collections.
Export publication-ready plasmid maps and images for articles and reports.

Pro tips
Use the built-in feature database for automatic annotation—it speeds up labeling and improves accuracy.
Before experimenting, check the agarose gel simulation to avoid surprises on the actual gel.
For routine tasks, create a collection of frequently used primers and plasmid templates.
Use bulk actions when working with large sets of files — this saves hours of work.
Customize color schemes to suit your preferences: this improves map readability and reduces the risk of errors.
Comparison with PVsyst and CLO 3D
SnapGene: a tool for molecular biology, specializing in DNA sequence analysis, cloning, and PCR workflows.
PVsyst: software for modeling solar power plants, analyzing energy production, and evaluating the efficiency of PV systems.
CLO 3D: a program for 3D garment simulation and creating digital clothing prototypes.
System requirements
OS: Latest versions of Windows and macOS.
CPU: Modern multi-core processor.
RAM: Minimum 8 GB, optimally 16–32 GB for large projects.
Disk: SSD for storing plasmid files and faster performance.
