Codon Usage

Codon Usage accepts a DNA sequence 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 or FASTA sequence into the text area below.

Enter the codon table you wish to use for the genetic code (in GCG format). The default codon table specifies the standard genetic code.
