Waiting for a sequence
Paste a sequence above. Nothing runs until you choose an operation and press its button.
03Configure Operation
Set the options for Complement, then run it.
Complement
Pairs each base with its partner (A–T, C–G) and keeps the input’s left-to-right order. For the opposite strand written 5′→3′, use Reverse Complement.
Input type
FASTA headerThe current input has no header.
Complement keeps the input’s order, so the result reads 3′→5′ under a 5′→3′ input. IUPAC ambiguity codes are complemented too (R↔Y, K↔M, B↔V, D↔H).
