DNAGenIQ - Random DNA sequence generator
DNAGenIQ generates random DNA sequences with customizable parameters for testing and analysis. Configure GC content, sequence length, and restriction sites.
DNAGenIQ generates random DNA sequences with customizable parameters for testing and analysis. Configure GC content, sequence length, and restriction sites.
DNAGenIQ generates random DNA sequences with controllable parameters. Synthetic sequences serve as negative controls in sequence analysis, test datasets for bioinformatics pipelines, and placeholder inserts for cloning vector design.
ProteinIQ runs DNAGenIQ directly in the browser with instant results and no account required.
| Setting | Description |
|---|---|
Number of sequences | How many sequences to generate (default 1) |
Sequence length (bp) | Length of each sequence in base pairs (default 200) |
GC content (%) | Target percentage of G and C nucleotides (default 50%) |
Add restriction sites | Toggle to include enzyme recognition sequences |
Restriction sites | Select which site to add: EcoRI, BamHI, HindIII, PstI, XbaI, or SalI |
Sequences are returned in FASTA format with automatically generated headers. The output can be copied or downloaded directly.
The GC content parameter controls the ratio of guanine and cytosine to adenine and thymine. Natural DNA varies widely: bacterial genomes range from 25% to 75% GC, while mammalian genomes average around 40%. Setting GC content to 50% produces a balanced random sequence; lower values create AT-rich sequences, higher values create GC-rich sequences.
Restriction sites, when enabled, are inserted at the sequence termini to facilitate downstream cloning workflows.
