Sequence Manipulation Suite:
Codon Usage
Codon Usage accepts one or more DNA sequences and returns the number and frequency of each codon type. Since the program also compares the frequencies of codons that code for the same amino acid (synonymous codons), you can use it to assess whether a sequence shows a preference for particular synonymous codons.

Paste the raw sequence or one or more FASTA sequences into the text area. Input limit is 500000 characters.

Please check the browser compatibility page before using this program.
