## What is DNA ToolBox?

A mobile DNA analysis tool for life science researchers, students, and bioengineers. No internet needed; all sequence analysis, primer design, and experimental calculations run locally, handling molecular biology tasks anytime, anywhere.

Core Functions
Sequence Analysis
- DNA/RNA sequence normalisation, reverse complement, and transcription translation
- Three-frame protein translation for quick view of potential coding products
- Instant calculation of GC content and molecular weight (single/double strand)
- Sequence formatting with one-tap copy to standard format
Primer Design
- Automatically generate forward/reverse candidate primers from template sequence
- Real-time display of Tm, GC content, and length
- Smart alerts for hairpin structures and self-dimer risks
- One-tap copy or save to personal primer library
PCR Simulation
- Simulate PCR amplification with template and primers
- Automatically calculate product length, theoretical yield, and GC content
- Auto-verify primer matching and correct orientation
Advanced Toolbox
- ORF Finder: scan six reading frames for open reading frames
- Codon Optimisation: optimise coding sequences for hosts like E. coli
- Plasmid Map: circular visualisation of DNA features
- Sequence Alignment: global pairwise alignment
- Restriction Site Scanning
- FASTA Import/Export
- Experimental Calculations and Lab Notes
Project Management
- Save sequences, primers, and experimental data as projects
- Local persistent storage to protect research privacy
- Quick access to recent projects from the dashboard
Use Cases
- Classroom experiment design
- Routine lab sequence analysis
- Quick validation before primer design
- PCR protocol rehearsal
- Gene sequence archiving and management
Make DNALab your portable molecular biology lab.
