How to use Random RNA Sequence Generator Online

Generate customizable random RNA sequences for design and testing.

Create batches of RNA sequences with a chosen final length and GC target. Add optional start and stop codons, untranslated regions, a poly-A tail, short stem-loop motifs, and pseudouridine substitutions. Presets fill common mRNA, miRNA, tRNA, lncRNA, and unconstrained RNA settings; every setting remains editable. Download the result as FASTA and review length, GC percentage, and pseudouridine counts in the summary.

How Random RNA Sequence Generator Works

The generator builds selected sequence features first, then fills the remaining positions with randomized RNA bases. When enough variable positions remain, it selects G and C bases to reach the requested overall GC percentage. Fixed motifs and a long poly-A tail can make that target impossible, so the summary reports the actual GC percentage. Start and stop codons use AUG and a random UAA, UAG, or UGA, respectively. The optional 5′ UTR ends with a Kozak-like GCCACC motif; each stem-loop motif contains a four-base stem, four-base loop, and reverse-complementary stem. Pseudouridine replaces approximately 10% of U positions in the randomized region.

These are synthetic sequence features, not predictions of expression, folding, processing, or biological function. In particular, added stem-loop motifs are designed to be self-complementary but their structures are not energy-validated. A generated AUG-to-stop segment is not guaranteed to be an in-frame open reading frame. Pseudouridine appears as Ψ in the FASTA output, which some sequence tools may not accept.

What is Neurosnap?

Neurosnap is the leading platform for bioinformatics and computational science focused on expanding access to powerful modeling and simulation tools.
