How to use Reverse Complement Online

Reverse, complement, or reverse-complement DNA and RNA sequences.

Convert pasted nucleotide sequences or uploaded TXT, FASTA, and FASTQ files. The service supports DNA and RNA, IUPAC ambiguity codes, multiple records, and optional preservation of letter case. Choose reverse, complement, reverse complement, or all three transformations for each valid sequence.

How Reverse Complement Works

A reverse complement first pairs each base with its complement, then reverses the sequence to report the opposite strand in the 5′ to 3′ direction. DNA pairs A with T; RNA pairs A with U; C pairs with G in both. Ambiguity codes are complemented to their corresponding IUPAC codes. With automatic sequence typing, each record containing U but no T is treated as RNA, while a record with T or neither base is treated as DNA. Records containing both are invalid.

FASTA records are processed independently, so invalid records are skipped and listed in the warnings while valid records remain available. FASTQ input is validated as a complete read set. Reverse and reverse-complement operations reverse quality strings alongside the sequence, preserving base-to-quality alignment. Select Same as input to retain FASTQ quality scores; FASTA and plain-text output omit them with a warning. The results include a downloadable sequence file and GC percentage calculated from canonical bases in the valid input records.

What is Neurosnap?

Neurosnap is the leading platform for bioinformatics and computational science focused on expanding access to powerful modeling and simulation tools. Because many state-of-the-art machine learning systems remain complex to install, configure, and scale, Neurosnap offers a clean, browser-based workspace that removes the burden of infrastructure management, dependency conflicts, and command-line tooling.

Built for biologists, chemists, and cross-disciplinary scientists, the platform enables advanced computational workflows without requiring expertise in software engineering or cloud architecture. Researchers can launch analyses through an intuitive interface, connect programmatically through a comprehensive API, and rely on automated resource management to scale workloads efficiently. By taking care of the underlying compute and operational complexity, Neurosnap allows teams to devote their energy to scientific progress and faster iteration. Security and data protection remain foundational principles, with clear safeguards outlined in our Terms of Use and Privacy Policy to ensure your work stays protected.

Advancing Discovery with Reverse Complement on Neurosnap

Using Reverse Complement on Neurosnap could drastically accelerate DNA and RNA strand conversion for primer, cloning, and sequence-analysis workflows.

Flexible input: Paste raw, FASTA, or FASTQ text, or upload a supported sequence file.
Record control: Split raw text by line or blank line while preserving FASTA and FASTQ boundaries.
Format control: Choose FASTA, sequence-only text, or the input format, with optional header suffixes and FASTA line wrapping.
Quality alignment: FASTQ output moves quality characters with their bases when sequence order is reversed.
