DNA Reverse Complement

Compute the reverse complement of a DNA sequence.

DNA Sequence (5' → 3')

Length: 0 bases

Reverse Complement (5' → 3')

Description

The reverse complement of a DNA strand is obtained by reversing the sequence and replacing each base with its complement (A↔T, C↔G). It represents the complementary strand read in the 5' → 3' direction.

How to use

Paste or type a DNA sequence into the input field. The reverse complement is computed instantly as you type. Only A, C, G, T (case-insensitive) are recognized; other characters are preserved without complementation.
