DNA Reverse Complement Tool
Generate reverse complements, complements, or reverses of DNA sequences
A↔T, C↔G
5'→3' becomes 3'→5'
Reverse + Complement
How It Works
Complement: Swaps each base with its complement (A↔T, C↔G)
Reverse: Reverses the sequence order (5'→3' becomes 3'→5')
Reverse Complement: First complements the sequence, then reverses it
Example with "ATGC":
- Complement: TACG
- Reverse: CGTA
- Reverse Complement: GCAT
Welcome to the DNA Reverse Complement Tool!
A fast, accurate, and user-friendly tool to generate the complement, reverse, or reverse complement of any DNA sequence. Whether you’re designing primers, analyzing gene sequences, or studying molecular biology, this tool simplifies essential DNA transformations in seconds.
Key Features
🧬 DNA Sequence Input
Enter any single-stranded DNA sequence using standard nucleotide codes (A, T, G, C).
Example: ATGC
🔁 Three Essential Functions
Instantly generate:
Complement
Swaps each base with its complementary partner:
A ↔ T, C ↔ G
Example: ATGC → TACGReverse
Reverses the sequence direction (from 5’→3′ to 3’→5′):
Example: ATGC → CGTAReverse Complement
First complements, then reverses the sequence — critical for PCR, sequencing, and gene cloning:
Example: ATGC → GCAT
✅ Process Sequence with One Click

🧩 How It Works
Our tool follows the standard rules of DNA base pairing and orientation:
Complement
Each base is replaced by its pair:- A → T
- T → A
- C → G
- G → C
Reverse
The sequence order is flipped:5'-ATGC-3'becomes5'-CGTA-3'Reverse Complement
Step 1: Complement →TACG
Step 2: Reverse →GCAT
Final output:5'-GCAT-3'
This is especially useful when working with antisense strands, primer design, or restriction enzyme sites.
