Analyze codon usage patterns and frequencies in DNA sequences. Identify synonymous codon preferences and assess coding sequence optimization.
Codon usage analysis examines the frequency of synonymous codons in coding sequences. Different organisms prefer certain codons over others for the same amino acid, affecting protein expression levels and translation efficiency.
Analyze codon patterns in three simple steps:
This tool is useful when you need to:
Sample coding sequence:
ATGAAATCTGGAACTTCTGAGTCTTGGACCAAG...Use the Example button to load a sample sequence.
Analysis shows codon frequencies and preferences:
TTT(Phe): 8 (0.12) | TTC(Phe): 12 (0.18) TTA(Leu): 5 (0.08) | TTG(Leu): 3 (0.05)Includes counts and relative frequencies for each codon.
Q: What genetic code is used?
A: Standard genetic code. Custom genetic codes can be requested.
Q: Can I analyze multiple sequences?
A: Yes, separate sequences with FASTA headers or line breaks.
